I got this bumper with some model A parts I bought. Don't think its model A, but I've been wrong plenty of times. Later,Bill
It could be a factory bumper for some thing OR one of the many variations of accessory bumpers made for early cars before 1927 when bumpers were a factory accessory and none came with them except by special order. Pickups from Ford never came from the factory with rear bumpers. Bumpers were installed at the selling dealers from the first T pickups to the late 80s or even later.
It's not an A. Rears are 2 piece and if it's for a front, brackets are wrong and doesn't have that extra piece in the middle. maybe after market or who knows.
