Barrel tubes remain black, so I believe some of the brownish/purplish appearance in the photo may be from the flash; that said, for about the first 10-12 inches along both sides of the barrel tubes, there is some fading (top and bottom of tubes remain near perfect). As those barrels were stored for decades unwrapped in the leather case, I'm wondering if that barrel discoloration/fading might be the result of a reaction to chemicals from the tanning solution (the white felt case liner remains in very good condition)? There is also some fading of the niter blue on the trigger plate and trigger guard bow which might be from the leather also? I'm sure there are those here who might know if such reaction could occur. Barrel bores were full of dust and what appeared to be dried grease; but after receiving a good scrubbing last night, bores shine like mirrors. There are no primer rings around firing pin holes at the standing breech to ever indicate firing; the standing breech remains un-marred save for very slight rub marks where the extractor made contact on opening. I rubbed some orange oil onto stock wood last night, which stuff was quickly absorbed and served to darken the wood somewhat for a richer appearance. I'll probably apply the orange oil treatment again in the next day or two. And although I'm sure this piece likely has dried grease inside the frame and needs a good cleaning and proper lubrication; I'm not inclined to disassemble the gun, as I don't want to risk damaging screw slots and alignment. Thoughts?
