Give credit where credit is due, and that's to Vic.
I have only seen the 'L' on rifles that were also renumbered by the Finn's, with the Finn number stamped above the original serial number which was lined out.
Bolt has mismatched numbers, Bolt carrier has no numbers, Stock has numbers but so faint there unreadable also has a faint Tula star on stock. Butt plate has a small tula star. rear sight has a star. Yea i got it off of gunbrokers a few days ago.
