These little Ideal tools marked for Colt are scarcer than hen's teeth. Handle is clearly marked "44 C.M.R. & W.C.F." which stands for Colt Magazine Rifle and Winchester Center Fire. Colt only built two rifles with magazines...the Burgess lever action and the Lightning pump action rifles. Both rifles were chambered in the 44-40 which this tool would have been suited for. Also, the Winchester Models 1873 and 1892 were also chambered in this caliber...hence the "WCF" marking. Overall condition is NRA Antique Fair condition with a heavy brown patina. Markings are worn in places but the scarce Colt and Win. caliber markings are intact and completely legible. Good working condition with a fair mold cavity. Complete with sprue cutter.
