Got a repro stock and need to age it to match rest.
Needs slightly darkened and dirtied

What is preferred method/ staining ?

TIA

bees wax and sunlight

Thing is no matter what you do it'll look like an artificially aged stock, but short of redoing the metal to match the wood what's a boy to do?

I did a Mauser stock once by rubbing it with used motor oil and beating it up with a key ring full of keys. Looked like crap when I was done. Shame because it was a real pretty WWII vintage stock. Ah, the hubris of youth.

BTDT! still have it in a outbuilding somewhere, 50 years later. if the rats haven't eaten it.

Assemble and loan it to a neighbor for a season with a word or two to be careful. About Christmas, swing by and retrieve if from the back of his pickup.

Found some stuff about vinegar and steel wool
Also found that there are commercial accelerators.

vinegar and steel wood will turn any wood with tannin in it - black also called ebonizing

the black shelves in this mahogany cabinet were coated in the vinegar with the steelwool "dissolved" in it.

6-8% solution of potassium permanganate
