Not sure of the model and/or year but this looks to be a 1950’s MoPar Ashtray. I want to say that it’s late fifties. 1957, 1958, 1959 and possible fits are Custom Royal Lancer, Sayoy, Belvedere. Coronet and more??
In good shape and will clean up nice with some care. know has very minor pitting and aluminum ribbed surface is just dirty and may have very minor dings or dents. A great backup or user!
Please look at the photos close and be sure this is the one you need!
