Re: ‘49 22nd bumper jack

‘Tee’ section post, and removable bumper cradle are features of the 55/56 design.
My thoughts on your question and the jack shown in the photo:
1. Packard ‘numbered’ their 22nd & 23rd series jacks with the same part number independent of the jack’s design. The Packard part number did not appear on the jack hardware.
2. More than one jack design was used on the 22nd series cars. Typically they were divided ‘junior’ and ‘senior’, but I’m sure there might be a bit of ‘cross pollination’.
3. The Packard jack ‘post’ for the 22nd series was either a ‘Vee’ shape (junior) with the teeth rolled into the inside corner, or square (senior) with the teeth on an outboard face.. Yours looks more of a ‘Tee’ section and that design was not used by Packard until the V-8 cars.
4. The portion of the Packard jack that touches and engages the bumper is broad and has a pin feature that will fit into hole in the lower surface of the bumper itself. Yours looks more like a flat pad. The senior pin appears to be a separate cone shaped piece, while the junior forms that feature in the stampings.
I believe the correct jack for a 22nd car ‘junior’ will be stamped “ASM Co” with patent number numbers 2,266,760 for the post and jack, and 2,397,965 for manufacturing details of forming the teeth into the post. I don’t know the marking on the senior design that Owen provided a photo, but I suspect only the patent number will change, only because the square post was used before the ‘Vee’ shape.
It is documented that Packard provided different jacks within one series, typically segregated junior/senior, but your jack does not appear to be either of those designs. I’m still hung-up on the lack of the safety pin or lip to keep the jack from falling away from the bumper. That seemed to be a feature throughout the industry for bumper jacks, and, as others have pointed out, the 22nd and 23rd series bumpers had holes along the lower lip for that exact purpose.
I’m squarely in the camp that these jacks are good to look at and display with pride, but should never be used. I carry a hydraulic bottle jack just in case.
