PPSh-41 markings

[Finnlander]

Hello.

I got this deac. PPSh-41 and I'd like to know more about it. It is 1944 dated. I know nothing about it's markings. Any ideas where was it made, when was it made, or anything. All info is welcome. It is number precise.

I also found two marks from it's stock. Could they be to mark amount of enemies killed? Or perhaps a more mundane reason, like garrison, or such. I guess nobody knows that.

Thanks in advance!
