Late war M44 correct finish

[CRomanos]

Several years ago I bought a pair of what Centerfire called "battlefield pickup" M44s with 1945 dates. I'm finally getting around to cleaning them up and once I got all the cosmolene out of the stocks I found wood and nothing but - not a trace of shellac anywhere. So I'm wondering, what was the correct original treatment for these rifles, and what would be a proper modern version?

BLO? Possibly sent to the front entirely unfinished?

I was thinking I might use some Tom's 1/3 mix, but eager to hear other suggestions. Certainly open to leaving them unfinished, too, if that's correct for the rifle.

I had a stock in similar shape that I had to make my own stain and then used blo topped with tom's 1/3 mix. It came out great.

I'm thinking that the late war models would not have had that involved a finish. Found an article on mosinnagant.net that implied that they stopped using shellac to speed up production, but doesn't say what they went to, if anything

Should be done with t by now, but the correct finish for nearly all pre-war and war time Russian rifles was shellac. It's possible yours could have been restocked, but ...... reworks were nearly all shellacked
