For a live fire Mauer, you can find them at gun shows or even auction sites. They range in price depending on model and condition (as most antiques do). You should be able to find a 7.63 caliber in firing condion for 700 - 1000 I would say, but again if the condition is good and all the numbers match you could be looking above 1000 easily. Red-Nines run even higher (highest I've seen was around 5k for peak condition w/ matching numbers). It's expensive for sure. The MGC will run 250-350 most likely, but they're much harder to find these days (but not impossible, I saw a few up for auction around the holidays). The chrome ones seem to pop up more than the blued ones. You can strip the chrome, but remember that will be an extra cost. The plate job on the chromed MGCs is absolute garbage, so I have no idea why they even exist in the first place.
