Spot repairing a stock finish?

[Widows Son]

Hello, I hope everyone is well. I have a question about repairing an unsightly blemish to my rifle’s stock finish. I’m not exactly opposed to completely stripping and refinishing the whole stock, however I’d rather try to smooth over this ugliness if I can.
The pics aren’t all that great because of the lighting, but the finish has been chemically removed down to the bare wood on all the area behind the tang and in streaks down the comb and butt. The rifle is a Parker Hale Whitworth made in 1978 and appears to have an oil finish. It was in this condition when I bought it.

I was thinking a little thinners or acetone on a rag to clean the area, then some linseed oil. Bad idea?

Improper cleaning technique . If done by the manual the water won't run all down the stock. I would try to blend Tung oil over the damaged areas carefully feathering out the Tung oil to he existing finish. YMMV

Maybe some linseed or Tung oil thinned a bit, but no acetone unless planning a complete refinish. Suspect someone used a solvent when cleaning the bore. Just see acetone making things worse. I would enjoy as is and consider repairing later on.

Thank you for your consideration. Yes, it looks exactly like a strong solvent was drained from the bore through the nipple and run down the butt. There’s no telling how many homes this has had.
