Bullfrog,
The middle magazine is 5.56 X 45 HK 33/91 Magazine.
george g. I agree, the 9mm magazine isn't a Colt SMG mag. It dosen't appear to be any kind of Glock, UZI or MAC 10 either. Still unsolved.
what about a gustav M45? maybe an aftermarket sten?
I don't think it is a tec9 (no tab on the bottom)
not a colt (no mag release)
not a sten (no spot welded upper part)
I don't think it is an UZI or MAC10 because the stop is too near the feed lips. because of this it should be an smg mag that sits outside the pistol grip.
It's a TEC 9. Identical to the picture. Thanks Robert 2888. That makes all of them identified. Thanks to everyone who contribtued to the identification. Great job. I finally know what I have in the basement in addition to black mold, mouse droppings and gun safes.
