Here's the Soviet T-28 medium tank that I ballsed up the printing of and had to retrieve (http://mojobob.blogspot.com/2019/03/the-heartbreak-of-filament-run-out.html). In the end it turned out OK, but it could certainly be better.
I don't normally time myself when I'm painting things, but in this case I put something on the printer just before I started on this one, and it told me exactly how long I'd been going. So this model's painting, from go to whoa, took me about an hour and a half.

The figures are 15mm plastic Soviets from PSC. One of these days I'll get around to getting some greatcoated Soviets with the pointy hats from Peter Pig, but that is not this day.

I printed a spare turret as well, with the frame radio aerial.
Radios of any kind were rare in Soviet AFVs of the time (late 1930s to early 1940s) and probably only the company leader would be likely to have a radio capable of both transmitting and receiving, and troop leaders might only have a receiver. Command by flag signals were still a common thing amongst Soviet tank units at the beginning of WWII. So that means that I'll only really need one radio turret per troop, at maximum.
