I have recently obtained a SVT-40 from 1940 (Tula) (EU Deactivated) and it came with a sling.
Initially I didn’t think much of the sling since it was definitely not a Russian one and I couldn’t place it.
On close inspection I found out it is most likely a Finnish sling!

I can’t find any SA markings on the rifle itself so I’m wondering if it was usual that this combination of rifle and sling was common and used by the Finnish throughout the (Winter)War without restamping or anything.

Any information about the sling (in combination with rifle) is appreciated.

I hope the pictures are clear enough, I’m happy to upload more!

Cheers!
