Howdy guys, didn't know a better spot to put this in.

I've been restoring a sporterized 1918 Enfield Mk III* back to its original condition for a while now. Had hell finding a proper barrel replacement but finally managed to snag a NOS barrel and have it installed and have gathered the original parts, which leaves me with just one thing: wood.

Nobody seems to make reproduction wood for the Mk III, and only the buttstock was usable from the original. I've gathered all the pieces but they're different finishes and a couple are soaked in cosmoline.

My questions are:
- Best way to completely remove the cosmo without damaging century old wood?
- Best way to strip the finish to bare wood?
- Suggestions on a period correct military finish?

The buttstock has a finish that almost reminds me of Russian shellac like a Mosin.

Thanks for any input.
