If you truly want a nice stock and your willing to do the work of building a gun using your old parts call Dick Greensides at Pecatonica River Long Rifle Supply,
815-968-1995.
Before calling, measure the width of your barrel across the flats.
Then, go to his site using this link
http://longrifles-pr.com/stockscomponents.shtml
Search thru the various styles of stocks available noting in their description what barrel sizes they are made for. For instance, this Leman Fullstock is made for either a 15/16" or a 1 inch straight octagon barrel.
Note the Stock Inletting & Drilling cost and write it down.
This "Inletting & Drilling" cost covers shaping the stock, cutting the barrel channel, drilling the ram rod hole as well as cutting the lock mortice etc. Even though you will not want the lock mortice cut, the price is not reduced. It is the same price with or without that cut.

After you've found the stock shape you want, go to the "Stock & Pistol" prices and choose the grade of wood you can afford.
After you've chosen a length and grade, write down the price.

Once that is done, your ready to talk to Dick.
Tell him which stock style you want and which grade of wood.
Tell him
you do not want the lock mortice milled or the trigger mortice cut because you are going to install a different lock and trigger.
The cost will be the sum of the Stock Inletting plus the Wood plus shipping.
For instance if you choose the Leman fullstock in the very best curly maple (#5) the cost will be $47.50 + 350 = $397.50 plus postage.
If you choose the Leman halfstock using #3 curly maple (an excellent choice) the cost will be $47.50 + $125 = $172.50 plus postage.
You will have to finish the barrel channel for your barrel and tang, cut the lock mortice and the trigger mortice.
You will have to cut the stock for the length of pull and install the butt plate.
You will have to install the sideplate and trigger guard and whatever else you choose to have.
Then you will have to finish shape and sand the stock, apply any stain you choose and finish it with a stock finishing oil.
Yes, it is a lot of work, but less than building any of the other gun "kits" he sells because your barrel already has sights and a breech plug.
