Since a couple
of months Armourfast has become a stand-alone company (whereas previously
it used to be under the umbrella of Hät). I don't know if there
is a link to that change, but the latest edition of the Armourfast
T-34/85 kit has been substantially reworked and is now dimensionally
far more accurate than it used to be (although still with some issues,
as we will see below). Detail has been improved at the same time.
The green plastic in this kit is quite soft; something in between the usual styrene and vinyl, which is slightly annoying when sanding or scoring. The plastic reacts very well to MEK however, but paint adherence is low.
The hull is a two piece affair, to
which the, MG mount, rear engine deck, exhausts, fuel drums and driver's
hatch have to be added. (The hull is solid underneath the latter,
by the way.) These fuel drums
actually took me more time to assemble than the remainder of the kit,
as they are split lengthwise; the resulting seam at the ends is quite
difficult to fill without damaging the parts. Apart from this, I also
believe that most T-34/85 had three of these barrels, not two as you
get in the kit.
The sponsons are open underneath,
but you will not see much once the tracks are installed, partially
because they are installed far too close to the sponsons if you follow
the kit lay-out. I chose to build the kit OOB, but installing the
tracks a bit further away (vertically that is) from the hull won't
be difficult. The tracks are not quite foolproof, so be sure you get
the idler in front and the drive sprocket at the rear.
The turret comes in two main parts, with a two part gun assembly. The gun is off-set (a bit too far in my opinion) and the engineering of the kit is such that you cannot install it the wrong way around. The commander's hatch is a separate piece, and if you cut it along the hinge, you can build the turret with the hatch open. (You'd better fill the opening with a crew figure, as the inside of the turret is empty.) Installation of this hatch is not fool proof, so make sure you get the short "half" in front, and the hinge lined up (as I didn't...). Likewise, the gunner's hatch can be opened up too. In all the turret is not a bad representation of the real deal.
After assembly, which takes about 10 minutes (including cleaning up the parts, but excluding fixing the seam on the fuel tanks), you still have some sort of toolbox left for your spare's box.
I took the time to measure the kits against plans in  and  (which differ quite a lot between them) and found that the hull is slightly oversize, being close to 1/68. The turret, on the other hand, is a bit too small, coming closer to 1/75. As the sides of the hull have a slightly exaggerated slope, the relative difference in size between turret and hull is not readily discernable.
The version of the T-34/85 this kit is meant to represent is, for as far as I can tell, a Model 1944 from Zavod 183 with ZiS-S-53, single lid commander's hatch, twin ventilator domes at the rear of the turret and disk wheels. (I am not sure if the latter feature is consistent, however.)
PS: note that you get two identical kits in one box, as is customary with Armourfast kits.
Below are pictures of the kit, after
construction and with a coat of grey primer. I still haven't decided
on a camouflage scheme, but it will either be 4BO or Russian Tank
Below are pictures of the earlier release. I believe the pictures speak for themselves.
