Does anyone recognize this pistol magazine?

[William J]

This came back in the spare mag pouch of a WaA140 marked M1922. I thought that was unusual because it will not fit in the magazine well of the pistol.

It's dimple on the bottom reminded me of a HSc mag but the notch on the back of the feeder and the "hole" in the front was unlike anything I'd seen.

I appreciate any help! Thanks in advance!

Additional pictures. Apologize for the poor photos. Rainy outside and dark inside.

Indeed, later war production HSc magazine.

Thank you all for the help! Sometimes something turns out to be exactly what you thought... I had recently sold a wartime commercial HSc and didn't have one on hand to try the mag in.
