I recently bought a 1905 Orient Buckboard that was a project kit built a number of years ago in the sixties. The now deceased (at 94) builder lived near Rochester, NY and was friends with George Selden. Selden gave the builder an original Selden brass patent plate which he affixed to the car. I have learned that 10 auto manufacturers from the early manufacturing period paid royalties to Seldon for a while (presumably he issued one of these tags at that time) but that Selden never built any cars commercially. My question is: Does anyone know how common this brass tag might be? Thanks, JB
