Well, here's a development I did not expect... since I had the barrel off in order to switch out the recoil bolt... I decided I would strip & refinish the stock.
Honestly... it really needs it... the shellac is flaking off.
I also suspect Ivan slapped on some extra shellac at the last refurb, which made the forward end of the stock and the barrel cover really look like "govno" (Russian for "crap").
So... I'm picking up some Circa 1850 during lunch today. This will allow me to strip the shellac without touching the various cartouches on the stock. I'll be refinishing the stock with BLO.
