I believe Factory #74 (Izhevsk) Sniper barrels have a circle-C stamped on them. Like the Tula CH it can be poorly stamped or faint. Also, as with Tula guns, it can be present on non-scoped rifles.

Ridolpho,
The circle c mark is actually a concentric 00 and is an accuracy proof mark, it has nothing to do with snipers specifically. It merely signifies the barrel met accuracy standards. Every Izhevsh i own, '43 PU sniper, 1937 infantry rifle and 1948 M44, has it.
