What factory made this tank to me it looks likes a factory 112 late, but I can not be sure maybe someone has more info as I am new to the t-34.
Thanks

Well, Factory 112 it ain't: Wrong hull, wrong engine deck, and wrong turret.
It's probably closer to an earlier UTZ flat turret but it's not quite right for them either. You'd need to add a center hinge to the upper/lower rear plate, remove a bolt head from either side of the upper plate as well as addressing a lot of smaller issues (none all that hard to correct if you're so inclined).
The Trumpeter kits, though they get a lot of praise, are pretty flawed. At least if accuracy is your thing.
