It's totally useless because I don't own a car with metal bumpers that this thing can attach to. Having to feed my addiction for cool Blackhawk stuff,
I acquired this J-17 Lift-Post because I thought the condition was really nice. I don't think it was ever really used as its still wearing its original paint and decal. It also came with a promotional tag and instruction card all from 1948.
Here's a couple of links that show it advertised in some catalogs:
