Trying to identify some 50 rd magazines

[littlebob]

I guess I put something in the wrong place and still trying to figure it out. Maybe I should have put it here to begin with. The thread I started was under parts and ammunition. I didn't realize I was in the classifieds. I have two complete Magazines, a pouch and magazine housing. I can load 9mm cartridges in them. They are marked at 10,20,30,40 and 50. below the round count markings they all have SA stamped on them. Trying to figure out what they might fit. They have been around longer than I have which makes me think WW2 era.

Still trying to figure it out. All the images of Sten Mags have reinforcing where it fits into the receiver. Couldn't find much on the Madson. In my search I found a few links to some that look identical, but still not sure what I have. The floor plates on most of the ones I see are attached over the magazine and these are held inside the body of the magazine. One of the links says it a sig smg magazine, but still unsure what they fit.
