SVT40 P/O?
Need more info, such as year produced and if it comes with the mounts or not.
But it will probably be worth anywhere between $200-400.
Mosin scopes are in more demand, even though more were made during the war.
But SVT scopes don't fetch as much today. They're best used for completing SVT snipers, as most SVT snipers on the market are parted out anyhow.
"Russian Rearesnal Programs" or something of the nature.
If you have the original covers as well, you can tack 50 bones to the estimate.
