During the evolution of the T-34, there was an initial effort to upgrade the T-34 and it was called the T-34M. Another effort to upgrade the T-34, was the T-43. During this process various turrets and hulls were created to test out concepts.
The example I'm going to model is a prototype cast turret on a T-34 hull. Panzerart dropped a turret on the market of this prototype about a month ago and I snapped one up right away.
What I'm going to model is in the first attached photo/profile from one of the Tank Power books, cover shown below in photo 5. The 2nd photo, is the Panzerart box. Apparently 62 of these cast turrets were produced, so I will model one of these turrets that was pressed into service as in the profile, mounted on a standard T-34 hull. Per the turret drawing, the Panzerart kit matches it almost perfectly, except for the gumdrop site, which I am sure I have one in my parts bin. The 2nd drawing is a T-43 with this turret mounted. Most of the T-43 pictures I have or have seen, show a later turret with some changes and a commanders observation cupola at the rear, much like the cupola on the T-50 light tank turret.
Last photo is the bottom of the resin turret, where I have graphed the turret ring from a Hex turret to properly fit the DML T-34 hull.
Mark, if your out there and see this, correct me where I am wrong on the evolution story I spun. Thanks!
