Technical 1955 Chevy bumper jack?

Time to get rid of extra parts and would like to identify this bumper jack,30 years ago I took it out of a 53 Olds but its not for one and was told it looks like a 55 Chevy jack so can anyone identify it.

 

All most sure it’s not.

 

It looks GM to me but that is all I know about it.

 

I’m not familiar with Tri5 jacks, but TF trucks used a wind up bottle Jack.
It does look earlier than the 60’s bumper jacks I’m had and used.
@Johnny Gee has a few tri5’s. Maybe he can shed some light.

 

It's been a while but I seem to recall that the area that goes under the bumper was flat and not a hook I had a lot of them when I was selling 5,6 and 7 parts but I'm not quite sure.

here's a 55 - 56 for sale. they said Chevrolet used multiple manufacturers and they vary slightly depending on where the car was built

 

A long time since I looked at a ‘55 jack but that’s not how I remember it. Flat, like 1934 coupe said and I don’t recall a dimple on the base plate. Also 55 had a flatter base. However, no suggestions on what it might be.

 

Its definately not a tri 5 and not a 53 Olds.

 

Only one of them has original jack. The one in question by OP does not look correct.

 

My wifes 1973 chevy used a jack like that. It fits in a slot in the bumper

 

if the lug wrench goes with this set up it looks like it is for some large lug nuts

 

It’s outta a dodge

 

Lug on a Chevrolet were 3/4” ez way to tell.

 

They're great for cocking the bumper up at an angle after a couple of flats.
