styles of roadwheel were seen on the Jagdpanzer 38(t)
"Hetzer". The early style is pictured here, and
had 32 bolts attaching the wheel disk to the rim. In
December 1944, manufacture switched to wheels with 16
rivets instead of 32 bolts to simplify production (the
other Attack set is labeled "16-bolt", but they
are in fact, rivets). Despite being an early design for
wheel manufacture, these wheels were seen on Hetzers to
the end of the war. I would imagine that it was also
possible to see a mix of the two wheel styles on a single
vehicle as replacements were needed.
These resin wheels are pretty well made. There are a few minor pinholes in the resin, but nothing that can't be fixed. In fact, the one hole seen on the upper left wheel simply looks like a missing bolt, which often happened. Although my Hetzer kits are packed away, I am guessing that these wheels are meant to directly replace the plastic wheels in the UM Hetzer (early) kit, as that kit includes rather simplified late wheels. They will likely work just as well for the ESCI and Attack models, perhaps with a little modification to the mounting holes.
