I have an original .50 caliber Government (black powder cartridge) reloading kit that I'll be selling and am looking for feedback on market value and / or where to look for comparative cost figures. I know these were used in the trapdoor Springfield but also Remington rolling block and Sharps model 1874 falling block rifles and were most often carried by buffalo hunters and frontiersmen. The "tong tool" included in the kit was made by Winchester. The only pieces that are not original are the wood dowels that are on the cast brass bullet mold.
