It is a 49 for sure. Ribbed bumpers the lead sled guys put on a lot of cars and the taillights on top of the fenders. This would be a great rat. Neighbor has a 54 Plymouth sedan his Dad bought new. Car went through a tornado and looks it. Great patina. It runs well and he just needs to get it roadworthy and start rattin'. My 53 is basically a rat with a Maaco paint job. The rat rod / jalopy thing has gotten really big in Denver.
Plymouth, 49 or 50. Looks very restorable. With the whole rat rod craze, you could update the drivetrain and brakes and drive as is. It would draw a crowd at any cruize nite. Ford truck in the background. Late 40's looks solid.
