Bringing back a old “barn find” stock

[45flint]

I recently acquired a old Crosman 102 probably circa 1929. It structurally seems in good shape but it looks like it spent 75 years in a barn. I hate vintage guns that have a refinished stock that looks new. What’s the best way to get the stock looking good but still retaining the age patina? Here it is now and this is the good side.
