Got this from my grandfather years ago…..

Grant, if you clean up the gun, don't use abrasives on the wood or metal and don't use lubricating oil on the wood. It is alright to use 000 or 0000 steel wool or a product called Frontier Pads on the metal surfaces along with a small amount of gun oil.
Use a soft cloth to clean the wood and it is alright to use "some" commercial wood (furniture) cleaners on the wood but NOTHING that might remove any original finish.
Do not snap the hammers until you get the firing pins replaced and even then use snap caps to cushion the hammer. If you break a hammer you likely will never find a correct replacement. This gun is worth several thousand dollars. Treat it wisely.
