I have quite a few, but not a lot of pics. I'll look for some more. Here's a John Gallagher conversion of an OM flattop .357 to .44 special. Love this gun - my perfect packing pistol, whose only real competition in that department is my 4" S&W M-24-3.
New Model 50th Anniversary Flattop .44:
Old Model .30 Carbine s.n. 700
Old Army, the .30 Carbine again, and bottom is an OM Flattop .44 in the scarcer 7 1/2" barrel. It has a steel gripframe and later production grips, as you can see.
Old Model Super Single Six, custom work by John Gallagher again. Cut to 4 5/8", post/bead front and wide V notch rear sight.
I got a few more, but that's what I can lay hands on for pics right now. Just bought another OM Super Blackhawk .44 that's been cut to 4 5/8", I'm a sucker for a short-barreled .44.
