The Reality
Didn't find anything previously posted on the Odessa or STZ3 tractor, so have some background readings

The beauty of this is that due to the lack of documentation, it's ripe for WIFFery (particularly in armaments)

Note that the prevailing theory is turrets being salvaged from upgraded T28s.
This is the standard DP fitting.
And these are 37mm alternatives.
In one memorable episode, the tanks entered a village occupied by German troops and while under fire were able to tow away 24 German guns.[citation needed]https://military-history.fandom.com/wiki/NI_tankUmm.. time to drop an implied meme.
The Model
Everybody's favorite Steve Zaloga on the Odessa and the Vulcan Models' STZ3 tractor.
https://www.youtube.com/watch?v=NNxbh-fruV8So there's been some old (as in old in the 90's) Soviet/Russian model instructions when I got the build sheet show in my pic below).
This one strikes me as being a resin kit. The Russian illustration above seems to be from a scratch-build instruction sheet.
