Stop and consider whether or not you want to take the time to do it right. Your rifle needs new wood, and it needs to be reblued. Total for that will run about $400 if you do some of the work yourself ($150 for wood, $100 for rebluing, and a few parts, and lots of work), more if you just farm it out. You will likely have more invested in the rifle than it is worth (reblued 99s sell for about $350).
If you are interested in selling it as is, I am in the market for an 1899.
