Cunningham also was in possession of high-capacity magazines and ammunition for the M3 machine guns, which are also known as “grease guns.”

I see a Sten subgun and another I can't identify, but no M3 Greasegun.

I wonder where this homeless man picked up the hardware .....

These kinds of weapons flood the streets donchaknow.... a homeless man has to wade knee deep in these things his entire life. He only has to rinse off the blood of innocents (non-aborted, of course) in order to use them.

It's a Vz25, which is a copy/variant/relation of the CZ23, which was the first design to make use of the overhung bolt.

Close inspection of the better photos leads me to believe these were constructed from parts kits with new tubes, or re-welded from them.
