Anybody know what these mags are for?

OAL is just about 9 inches and they have a triangular shape. Probably about 9mm

Thanks in advance..

I have a heap of STEN gun mags I run in my Oly Arms .40s&w upper on my Oly AR 15; those are not Sten gun mags. I'm leaning toward Somui or maybe some thing that has mag catch in pistol grip like that Argentine Tube-receiver SMG...

So far I've figured out NOT Suomi, not Berretta SMG, not Argentine SMG... I'll keep looking

Not a MAT-49 French, not madsen M50, not Gustav/ port Said,

Not a UZI, Reising, Sten, M3 greasegun,

[scarry scarney]

Not Thompson
