Well ain't that pretty!? I have a collection of antique rifles, mostly old military bolt actions, and I can say that these steps have made everyone of those guns as good as... almost new.
1- check to see if it's loaded, I won;t repeat the steps
2- get a light coating of linseed oil on the stock. Real light indeed. many older stocks are dry to the point of being brittle.
3- clean the bore. Old times just plugged both ends and shook around some hot water, poured that out and wiped it dry. Use modern cleaning solvents for this one. There might be pitting deep in the barrel, try to look down it as best you can.
4- replace the ramrod- don't throw it away! Just put it up and get a new hickory one from that track of the wolf site, and cut it down, maybe stain it. I've seen old wood that had to be soaked in linseed oil to penetrate the wood (this is in dry as heck texas). Safer to get a new rod.
5- get some tools- I cannot say what your threads on the old rod are, and odd threads often have odd tools (hard to find and costly when you do)Go on and get som enew toosl for the new rod. Save your antiques for show and history. A new Lee bullet mold is about 20 bucks, and they're American made by God!
7- clean that lock- take off the lock and clean any evident gummed oil of the works with some spray and q-tips. Take your time and go slow.
8- have it looked over- get a pro to have his say.
9- be gentle- if you are ready, take it to the range and put light loads through the rifle. I would not hunt with this gun, but if you have to, be mindful of brush and such.
forgive me if I repeated anything.
