Please help me ID this magazine

I came across this magazine and I can't figure out what it goes to. From what I can tell it's 9mm and the only marking is a "Q" on the spine. Any help would be appreciated!

Hmmmm...was thinking Sten gun, but the cutout for the latch is upside down.....

 

[CapnMac]

Yeah, that reinforce at the top pretty much screams "STEN" as does the lack of witness holes and distinctive markings.

Double-stack, single-feed, 9mm not narrowing the field much, though. Sigh

 

[Dr.Rob]

Sten is as close as I got and I have been looking for an hour.

 

[Odd Job]

I also can't get closer than Sten or M3 grease gun mag.
The thing that throws me is there is no magwell stop on the OP's mag.

 

[Dr.Rob]

I'm almost positive it's a side locking mag. It's not possible one of the images is reversed?

 

[bersaguy]

Looks like an mp38 mag without the reinforcement ribs

 

[bersaguy]

So I agree with @Dr.Rob . Looks like the only locking surface is the D cut out on the one side, so a bottom loader would shake that mag out. It looks like it's just folded and spot welded, and a bit rough, so maybe a late war last ditch substitute weapon?

 

[Odd Job]

Oh I have found another contender: it could be a MAC-10 mag.

 

[Dr.Rob]

I looked at vergnon, Mac 10 , Madsen, Mat 49, Uzi, Sten, Owen, Sterling, FMP, M3, Czech smgs, Berettas old and new, Walther, Mp28, Mp 38 and 40.... Suomi, Bergmann MP32/35...

 

[Dr.Rob]

Lanchester maybe? I will have to look that up when I get back home.

 

[Sovblocgunfan]

MP-18? They are most commonly associated with a snail drum but used a box magazine in testing, and also late in production.

 

[Dr.Rob]

Mp18 has a final feed the size of a Luger.. and it appears later models used a mag similar Hmmm.

 

[Sovblocgunfan]

Yes, the mp-18 was designed for a magazine like the one in the OP’s pictures. It was redesigned for the snail drum used w the Luger. Then late in production the “mag well” was redesigned to accept the box magazine as originally intended.

So it’s a possibility...

Also could be a lanchester...

 

[Sovblocgunfan]

I think the OP’s magazine might be derived from the MP-18 if not copied directly. Pic here is of a Finnish M20. The M20’s were sold to Interarmco in 1960, apparently. Source: http://www.jaegerplatoon.net/MACHINEPISTOLS1.htm

Thanks for all the replies.

I actually think I figured out what it is! I believe it's an old AR-15 9mm magazine, I'm still not sure of the maker.

I found this posted on another forum and the magazine on the far right looks familiar.
