The pin shown in post #7 looks correct for a 'junior'. The 'Vee' angle should be 72 degrees, and the markings as indicated. The base will not have a small hole.

Ok here are the two jacks I have ....

I would say the 'Vee' post jack is a junior 22nd/23rd series jack . . . assuming the ASM Co marking is there, and the 'Tee' post remains unidentified.

The consensus of the forum members is to treat the OEM bumper jack with the greatest of respect, retirement is appropriate.

Don’t see any ASM markings .....so what’s the difference with junior/senior cars as far as the 22/23 series goes ?

I have heard the square jack is for the seniors, I would use it as it appears stronger. I believe the jack pictured in whats left of the correct jack box for 48 is for 55 or 56.

Dell is correct.

The square tube post with the cone to keep the jack aligned with the bumper is associated with 22nd & 23rd senior cars.

The 'Vee' shaped post with the alignment feature formed in the sheet metal is associated with 22nd & 23rd junior cars.

For Packard, the 'Tee' shaped post came later, but yours seems not to be a Packard jack because I didn't see the removable piece that fits the bumper.

Having said that I'm sure if you asked the salesman politely he/she would throw-in the 'vastly superior' senior jack. I'm not all that sure the square tubing design is in fact superior or stronger. I see one failure mode as deflection of the structure where the teeth are formed. My eye tells me the 'Vee' design would not deflect as much in the area of the teeth.

As a long thin column I think the square tube will carry more load, but that's my eye talking. The senior cars are likely heavier, but I can't believe anyone played that close to a safety factor of one.

At any rate we all think they're unsafe and can be displayed with pride, but not used to jack the car high enough to remove a wheel.

If your car is a junior the 'Vee' design has a higher probability of being correct. I'm surprised the markings are not visible.

The Henney-Packards to 1954 used a jack with the pin but those cars had large brackets attached to the bumper bolts for it and I would not have trusted it with three tons of weight! In fact, I would never use a bumper jack on a Packard but always good to have the proper one in the boot (trunk) for display purposes.

How do you recommend jacking the cars if a flat needs changing?? On the 1951-54 cars the rear body needs to be jacked up to make clearance for getting the tire out from under the quarter panel.

Use a hydraulic jack placed under the frame rather than under the suspension should allow you to lift and clear the fender issue. Perhaps a spacer (piece of 4x4?) to get a little extra lift.
