Very nice 43 Tula PU. I assume you paid extra for handpick Tula? I got a 43 Tula from AIM, same shipment of 1000 from Morlot and imported by I.O.. Mine was a definite shooter with 6 groups of 5 shots at 100 yds averaging 1.23 inches and 3 sub inch using Extra Match ammo.
Your scope is an early A prefix with 1943 date, and probably one of the last A prefix that had a date. Progress stopped dating theirs about the time yours was made. I can not tell that you have a Tula mount but bear in mind these guns are refurbed and parts are usually mixed and renumbered. For the price these are saleing for, they are a steal. That is why AIM sold out of Tula in about 30 minutes when first offered and sold out of the 500 they bought in about 3 days.
There are dozens of examples posted on gunboards collector's forum and sniper forum.
Congratulations on getting a nice PU. These are the best deal on a WW2 sniper and the PU will shoot with just about any sniper made in WW2.
