Replica of the Schneider and Glassick revolver, made by Giacosa Luciano Brescia (the GLB) in 1971 (the XX7 date code). There should be an importers mark somewhere on it. But from the maker and date, it's probably an FIE (Firearms Import and Export) or EIG (Eig Cutlery) import. The maker and importers are long out of business. From the pictures, it is in excellent condition and should fetch anywhere from $150 to $175. On a really good day, it might bring $200
