They make the 50 cal, they make the turret mount, you even make the railing which one arrived broken, same with one side of a tiny detail of one of the 50 cal had the other 50 cal not arrived in tact I would only be able to tell because the gun were symmetric in every other detail. All that aside,
Why don't you make the gun belts?
These boat cranes have excellent detail to them, although they are just slightly larger than the kit provided one. Unfortunately, I broke both crane “arms” when I was cutting them off of the sprue so I ultimately had to use the kit provided cranes.
