construction article you may consider to be part two of my
kit comparison I posted several years ago. The companion vehicle
for this 3.7-cm Flakpanzer, I consider the Wirbelwind Flakpanzer which
has the same chassis but with a four gun 2-cm Flakvierling in an open
top octagonal turret. Below I'll assemble both models side by side
for a compare and contrast look at them. Observations on these two
1/72 scale Ostwind kits are very much the same for Hasegawa's
Wirbelwind kit 31148 MT48 and Maco's Wirbelwind kit 7215 which
share many parts, primarily the hulls and suspension. At this time
I believe this Maco kit will in time be re-released by Revell, as all other Maco kits.
Starting with the kit's box art we see what we are supposed to end
up with when done, more or less. The turret and gun parts are new
moldings from Maco Company while the hull and suspension is from the
respected 1/72 Revell Pz IV Ausf. H model kit. The MACO kit box above
shows what looks to be a late production Pz IV chassis like an Ausf.
H or J, probably factory built as an Ostwind (East Wind). This vehicle
identification is based on the lack of a driver's side viewport, lack
of Zimmerit coating and the late style sprocket and idler wheels.
rollers are four rubber tired wheels, not steel wheels. See part
one of this kit review for further information and discussion
of the box art: Notice that the flap for the gunsight right (our left)
of the gun is lowered, open, so the weapon can be fired against low,
perhaps ground, targets.
color of this Ostwind in this boxart appears odd to me in that it
looks pale gray when it should be dark yellow; bad lighting?
The Hasegawa box art for their Ostwind kit shows a similar vehicle
to the Maco box art. A significant difference between the two Ostwind
artwork is that there is a side visor for the radio operator (and
therefore the driver also) and a different headlight; this implies
to me an earlier model Pz IV hull. The difference in camouflage scheme
between the hull and turret also implies a rebuilt Panzer IV Ausf.
G. Other little details like the older style headlight and older sprocket
style imply this is an older variant Pz IV hull than the Maco Ostwind
model. Go to the in the
in-box preview of these two model kits with more information.
the Assembly & Detail
Both kits are good quality, well molded model kits and pretty comparable
in approach to molding the kit parts, though I found Maco parts
to be more accurate and delicately molded. The Maco model kit is actually
made up of pale amber styrene plastic parts supplied by Maco and tan
plastic parts from the Pz IV Ausf. H model by Revell AG, therefore
I will refer to the kit as having Maco parts.
Above we have a comparison of the gray Hasegawa turret parts at left,
and the pale amber Maco turret parts at right. Both are pretty similar
but for a few differences, such as: different shapes to the spent
ammunition pan, a different type gunsight. For a good review of the
Maco Flak 43 gun kit with ideas for detailing it please go to the
review by Al Magnus.
turret has a thicker wall thickness with locater pins and holes which
will show up as small bulges on the inside; the Maco turret we must
carefully glue together and align the sides to make sure it is straight.
Note how Maco's upper turret part (part-A4) has the notch cut out
for the gunsight opening. With the Hasegawa part L-5 we must scribe
in this gunsight opening.
The photo above displays the additional detailing to the Hasegawa
Flak 43 gun with white styrene strip and rod, and the scratch-built
spent ammunition baskets made with wire and fine mesh. On the Maco
model below we can see the mix of the light amber color Maco parts
and the darker tan Revell parts. I understand the reason for the new
upper hull in the Maco kit is that the Ostwind had the turret ring
further aft than the turret ring of the Pz IV tank, a fact the Hasegawa
kit appears not to have accounted for. If you examine the two kits
you may see that the Maco kit turret is accurately mounted further
deck of both models features grab handles simulated with fine brass
wire. On the Hasegawa model, representing a rebuilt Pz IV G hull,
we have a chipped and damaged Zimmerit coating, and the spare roadwheel
box on the port side. With the late war Ostwind model we have the
spare roadwheels mounted on the rear on either side of the exhaust
pipes, and the four steel return rollers characteristic of a Pz IV
This rear, overhead view we get another view of the differences in
the hull between a 1945 Pz IV and a 1943 Pz IV, such as the difference
in tow hook and fire extinguisher positions on the front port side
fenders. On the rear of the Hasegawa Ostwind hull we see the large
exhaust muffler typical of most Pz IV AFVs; on the rear of the Maco
kit I have scratchbuilt two Flammentöter (flame-suppressing)
exhaust stacks used on late war Pz IV hulls.
the turrets are my scratchbuilt renditions of the mesh spent ammunition
baskets on the right side of the Flak 43 gun. These are based on the
limited interior photos of the Ostwind that I was able to find.
The Part company etched brass Zimmerit coating designed and sold for
the Hasegawa Ostwind and Wirbelwind model kits, applied carefully
with cyanoacrylate (super) glue. Unfortunately, when I built my models
I did not have any etched brass for the Ostwind turret nor Flak 43
offers an etched brass fret #P72058 for the Hasegawa Ostwind model
with what appears to have a near complete Ostwind turret made of brass
plate that folds into shape. The great thing about this brass turret
is that the armor plate is close to accurate scale thickness. As a
nice extra, it has a nice mesh spent-cartridge basket. Brass set #P72056
for the Hasegawa Ostwind offers three frets with new hull fenders,
hatches, tools sand turret interior parts. At the time I write this,
I have not found any etched brass for the Maco Ostwind kits
though I suspect and hope these etched brass sets would also be usable
on the Maco models.
go to a specialized shop such as Tracks
& Troops we may find a plethora of aftermarket brass frets,
resin wheels, replacement track and brass gun barrels for the Pz IV
As the Ostwind and the Wirbelwind both appear to have been built upon
rebuilt Pz IV chassis, the hull could have a Zimmerit coating but
not the turret. Part company offers an etched brass Zimmerit set P72-070
in 1/72-scale for the Hasegawa kit so as to build a more accurate
Ostwind or Wirbelwind model. My previous experience is that the set
assembles well and looks good on the model. Part also offers set 72-071
that has simulated Zimmerit that is chipped and damaged.
brass Zimmerit pieces may also fit on the Revell Pz IV kit but without
guarantee. I notice there are no visors for the hull sides suggesting
this set is for a Pz IV Ausf. H rather than a Pz IV Ausf. G chassis,
this etched brass Zimmerit fret would not be appropriate for the Maco
Ostwind or Wirbelwind kits.

half and the wheels and track. Don't forget to simulate the metal
straps holding the muffler on. On the superstructure’s starboard
side we see the long box for spare gun barrels mounted on the fender.

the tow points made from the extended hull side plates, simulated
with white styrene sheet. I like that the Maco offers open
driver and radio operator hatches while the Hasegawa hull has these
hatches molded closed.
Skipping ahead to final assembly: The Maco Ostwind model with
soft edge 3-color scheme and light weathering. The paint scheme and
details for this late variant Ostwind are based on historical photos
I found. Notice the open gunsight flap for ground level targets.

I am thinking that perhaps the gun sight should be a dark gray of
Now that it is done I see annoying imperfections and mistakes, such
as the imperfect seam below the gun barrel where the upper and lower
hulls are joined.
The Revell link & length styrene plastic track looks good and
is easy to work with. Yes, there are no markings, matching some references

Interesting, no tow cable. The location of the spare roadwheels is
similar to those on the Sturmpanzer Brummbär.….
Hasegawa Ostwind model finished in overall winter white with no visible
markings. The visor on the starboard hull side for the radio operator
confirm a rebuilt Pz. IV Ausf. G or F hull. The soft plastic tracks
with the Hasegawa Pz IV kits are their worst feature and really should
be replaced for a good display model. We can use a number of aftermarket
Pz IV tracks, or do what I did and cover the track in ice and snow
to mask the poor track detail; I knew I did not have an award winning
model with this kit so did not care much.
Don't forget to add the cross bar to hold the spare roadwheels in
their storage box.
Based on a winter of 1944-1945 photo the only marking is a single
Balkenkreuz on the rear, set into the Zimmerit texture with lots of
decal setting solution. The tow cable has been reproduced from a teabag
string coated in white glue.

then rubbed down to a light gloss with graphite from a soft pencil.
Both 1/72 scale model kits build into a convincing small-scale reproduction
of the Ostwind Flakpanzer. The Maco Ostwind and Wirbelwind
kits are clearly superior in detail, tracks and suspension and accuracy.
If I were a novice or wargamer I would choose the Hasegawa kits which
I assess to be more robust.
