Ok im a little confused SEB Team
The mortars you have made, what are they actually meant to be? I suggested earlier you make a small 60mm, and make it portable.
Both the ones you have made are identical to look at, one being named 'M19' the other NVA/VC 60mm. The M19 is a 60mm mortar also, but the ones i have seen all had a square base plate, not round, and much smaller.
Because of the size you have made them, i would say they more represent the larger 81mm or 82mm mortars.
