This is a 28mm model of the Red Army’s 37mm AA gun, Model 1939.
First thing to do after printing the parts, please glue the Gun mount to the gun mount bottom (both are approx 39mm). This gun mount will then sit on the actual gun base.
I tend to sacrifice accurate scale on smaller parts in favour of making the model more robust, but I did include the various elevation wheels and sights represented on the actual gun. I made the gun barrel movable; although do take care mounting it in the pivot points. I made a trough in the gun mount to help ease it in.
The wheels/tires have a “flat spot; please make sure that goes towards the ground. I thank .kpi for his 40mm bofors file, on which I used as a starting point for this model.
If you have any questions or suggestions, please drop me a message.
