What is the consensus on the scope retention notch for the 1941 Tula at 1941 Tula SVT 40 (ex-sniper) - Album on Imgur ?
The notch shown on your SVT 40 receiver is exactly the same notch on my SVT 40 sniper. The Tula factory notch is a fairly wide deep almost square U shaped notch. I assume it could be a field armorer installed notch especially if the bluing is the same on the rest of the receiver. No way to tell for sure if it is a field expedient notch or a forgery. I am in the same boat with mine.
Can someone please post a photo or link to a photo of an authentic, factory produced Tula scope retention notch?
Yes, i would go with "field armorer installed" as well.
Does anyone know what the following marking at the rear left of my SVT 40 receiver could be - hammer and sickle?
