Stain , I use is Fiebings . I get it from Leather Unlimited , by the quart bottles. I buy black , tan ,red ,yellow , and orange. Those colors , pretty much , can stain most any wood used for guns , and a bonus , it's leather stain so , good for that as well. Fiebengs is sold by woodworker's stores , and Tandy Leather. All this stuff is on line. All these stores have the smaller bottles as well. I use enough of it , quarts are handier for me. That Leather Unlimited , has bundles of what they scraps cutoff from cow bellies. These cow belly scraps make fine slings , and straps for shot pouches , etc. ,Hope you've found all this , at least , amusing. I've been building m/l guns for over a half century , not for profit , but for fun. I won't give anyone something , I wouldn't use myself. I've built some fancy copies of famous guns , but find the work tedious , and few folks will , or can pay for what it's worth. On the frontier , guns were tools for defense , for getting food , and amusement. I have a number of popular books about life on in 18th century frontier , and nowhere ls there described , a frontier man sitting on a log admiring his expensive rifle. Guns , mostly, were purchased using animal skins , in an extremely frugal economy. Man , I'm off in the weeds , again.Luck to ya...........oldwood.
