So this might be a real frankenstein, a too big gun on a rather small vehicle.
So here I go, bit of new kit of the Dragon 1/35 BMP-1 and a pre-loved, very ordinary Skif BS-3 100MM Gun

A bit of hackage to get the top off and starting to add a few bits and pieced that sort of look like the BMP-1 interior and shuffle some stuff around.
Early days yet. One thing is already apparent, which the thought bubble did not suss out.. loading this sucker is going to be "interesting".
Probably work on a procedure where the gun is taken to max elevation so the loader/s do not have to hoik a 100mm round over their head. Or something like that.


Now apparently, the steadfast folks in the Ukraine are using these guns from 1944, mostly in a field gun role, but the interwebnet mentions and unconfirmed report of the BS-3 on an MTLB chassis, so who knows, this might actually be out there. The BMP-1 is a much smaller and lighter vehicle though.
