Headstamp Identification 9x19

Hey,

Got these 9x19 (which i think self reloaded) cartridges a few weeks ago.

I have never seen this Headstamp before. Maybe Finland?!

Thanks for your Help!

Regards, Mathias

Yes, Finland. S and SO is Sako AB, Riihimaki. WWII production.

Finland (SAKO Manufacture) is correct, BUT NOT with this homemade lead bullets.
The loading is NOT orginal to this headstamp…

Thanks gentlemen. Yes, they are homemade. There were a lot of other different headstamps… it is not the first time i get such selfmade cartridges with this bullet…
