Asked the question on a different post which veered off topic. The question, is the Inverness a copy of a DMB?
There seemed to be a following the Inverness is a Rizzini copy, and a DMB. In viewing photos of all three guns, the Inverness look closer to a DMB, than a Rizzini, for the internal working I have no clue.
Does anyone know the differences?
