Picked up these two, a matching numbers 42 byf black widow and a 45acp Luger. Also picked up two Colt ace 22lr built on aftermarket frames. The 45 Luger was built in 1970, was told it was one of John Martz first working prototypes, has a modified 1911 magazine that works when it feels like it. Gun works great with the magazine luger an builds, 300 a pop it should work. Now to get the two Colt ace 22s out to shoot them.
