Recent find at a sportsman auction is this: Vintage 1950’s Sears Roebuck & Co. – J. C. HIGGINS Gun Cleaning SOLVENT No. 671 for ALL Firearms. It appears this was purchased and never opened. It Nitro Powder Solvent bottle contains 100% of the original contents and the paper labels on the glass bottle are MINT. The cardboard box shows very little shelf wear at all and should make an outstanding addition for someone’s collection of antique and vintage hunting memorabilia.
