Old Cadillac taillight. I think it is a 1935 or 1936 but I'm not sure. The housing has some pitting. The glass lens had a chunk broke off and glued back on (last picture). I have had a lot of car parts over the years but never one of these. It may be better suited for a bobber motorcycle $275.00 Shipped in the U.S.A. Contact me through PM. Thanks Bruce
