Please be aware that a number of doublegun stock specialists are doing amazing repair work and an evaluation might be worthwhile. Repair is likely to be MUCH cheaper than replacing the stock, and your L.C. Smith will still have the factory stock. If you post your need and general location on the Forum, a LCSCA member may be able to recommend someone near you.
Stock repair examples
If a replacment stock is your only choice, you will need to match the gauge, frame size (Regular or Featherweight), and production era (Syracuse, Pre-1913, Post-1913, Post-1945.) Even so, the replacement stock WILL require additional fitting to your action and may need glas bedding and repair of cracks in the head of the stock. It is also quite possible that the fitted stock will have less than optimal dimensions (short length of pull or excessive drop) and will require bending or the addition of a period appropriate butt pad http://www.lcsmith.org/faq/recoilpad.html
Original Hunter Arms Co. stocks are occasionally listed on E-bay, gun auction sites, and internet forums including:
Another option is to purchase a new partially shaped and inlet stock. It is very likely that a stock specialist will need to do the final fitting and checkering, but you may then finish the stock as you wish.
Sources for partially inlet stocks:
Bob's Gun Shop
Wenig Custom Gunstocks, Inc.
The last and several thousand dollar option would be to have a new stock made from the wood blank that you select. You might consider a session with a stock fitter to establish the perfect stock dimensions based on your body habitus, shooting style, and primary shooting discipline- wingshooting, skeet, sporting clays, or trap.
