Ian has some special interest on some special items, and posted excellent reviews on youtube.com. If interested, here are a few videos:

There are many more. It's interesting to notice all handmade were blowback type. I believe that's still the situation today. From news, police captured handmade pistols here and there, destroyed one in-home gun making facility after another. On display, all were blowback. No complex ones.
