I got this from a old dump site that was located at a old gold mine. The fella who gave me this (older fella) told me it came off of a original 1920s truck. Now don't hold me to this question, But he used the motor and axles out of the vehicle for running something at the mine. So now that i'm thinking about selling it, I can't be for sure what he did say. I goggled (WHAT WAS THE FIRST YEAR OF THE BUCKET SEAT) and i get different results. This was a two piece bucket seat. The bottom half being bolted or riveted to the top piece and the top., You'll see the upper piece was molded around the outside edge of the seat. Any info would be greatly appreciated.
