Topic: Decipher Magnum 500 stamp codes?

[squally70]

Hi, first post of many I anticipate, was directed here by a VMF member in hopes of a little more detail. I've had my 70 M code vert since 82 but that's for a different thread.

I bought these brand new 12 or so years ago from a guy that told me he "had 'em made" to my where'd you get them, but people are saying no. What do the stamp codes say?  Thanks!

Welcome

To get things started here are two earlier related threads that I found using the words "Magnum wheel marking" that might provide some insight

Thanks, really helpful determining authenticity. Now to patiently await what they mean..

We already know that 14 is the rim diameter (at the tire bead) and the width is measured inside of the rim from one inside bead to the other.
The JJ is standard nomenclature/code  for one of the outer rim profiles. Imagine the wheel cut through the rim and the profile that results. There are many more than the versions in the picture.
The odd stamping within the circle says the wheel manufacturer is a member of the Tire and Rim Association. The TRA has 3 sub-stamps. Members like Kelsey Hayes appear to have used the single stamp as noted in the 6-10 o'clock position of the brand logo. I'm not sure if the logo on the rim is one of the three noted in the pic.

I'll let others give their hand at some of the others. Some wheels do use a circle with an alpha letter in the center (month) with a numeric day inside or stamped next to the day. Read as circle D 2.

Edit to remove bad data.
