Guest need4speed Posted March 10, 2013 Share Posted March 10, 2013 I have two round solid brass caps. They measure outside diameter 2.55 in....inside diameter 2.275 in and they are a 1/2 inch tall. The are inside threaded at 12 threads per inch. The outside of the cap is heavy knurl. They are not plated...brass with patina.The inside of the cap is stamped: L.B with a lined box around the letters and the part number M 1296.What is the manufacturer stamp L.B? Are these motorcycle gas caps? Radiator caps or auto gas caps? Link to comment Share on other sites More sharing options...
