There isn’t a lot of history written on this type. It appears it showed up just after the Great Patriotic War, so wasn’t in use during that time. Still, it does seem like it was in use for quite some time.
The Kit
The PST IS-2MT consists of 157 parts. While there are actually more parts on the sprue, there are about 157 pieces that are used with this kit. No decals, as it appears these were extremely plain machines, finished in all-over green without any markings.
Construction starts with the lower hull. After the sides are added to the lower part then the rest of the smaller parts can be added. These parts include towing pintels, etc. but also include all the running gear. After this area is painted then the link-and-length tracks can be added.
The rest of the kit should go together easily, once the parts are cleaned up. Since there isn’t a turret per se, there isn’t much to add the upper hull. Some small parts like fuel drums etc. are glued on before adding the turret “cover”. Basically it looks like a flat piece of metal used as a place for a cupola for the person controlling the tank to look out of.
After all of the parts are added to the upper hull then the upper hull can be attached to the lower hull.
Conclusion
Another winner from PST, albeit of something unusual. The most difficult aspect of this kit will be the clean up and the addition of the link-and-length
