It actually really is a copy of the Coehorns and the other mortars that the French pulled from the museums in WWI. That apparently gave them the idea for these. They needed anything they could get because the Germans, as always, had the best equipment. One of the British versions used a cut down No1 Mk3 Lee Enfield to launch the projectile. Cutting down a Enfield would require and C3 mfg license and (the Enfield) would become a dealer sample AOW. Not worth the expense. if I build one it will be fuse fired or percussion fired.
Well I'll avoid discussions and pics of WWI and later devices.
