Is this an MP40/38?

[David-lindstrom]

Hello all, i just joined and and i already have a bit of a mystery gun. It is in the background so not the best image but here it is:



The underfolder looks about right, and a few frames forward you can see the end of the barrel and the front sight, briefly and in the background: But it looks about right.

It is the backend of the gun that has me puzzled, it looks like it just ends in a 'tube' shape and not the more rounded off end that you find when you look at MP38/40 images.

Please let me know if you have any guess to what it is!
