With some "Continental" guns you just have to label them "a nice team effort"! That Italian/German/Belgian wartime gun that Bugeyed Monster was asking about a while ago is a good example.

Finding "The" maker only matters when you go to sell the gun....to the rest of us it's a matter of interest, for sure, but not the most important one. I'd say the safety and quality of the gun are what's really paramount.
