Arisaka Stock Color Question

[MilsurpMM]

this is an example of a late production type 99 short rifle in a rope hole configuration. the grain is not as pronounced as another rifle i will get some pics of tomorrow. but the stock finish is a flat dark brown and is original.

That's interesting.

I don't know if you noticed, but the lower half of my rifle's stock is very similar to your rifle's stain color.

I'm confused why the lower half of my rifle absorbs the stain so differently than the rest of the rifle. I mean, it's the same stain used so how does that work?
