Looks like I have a Oldsmobile one that hasn’t been accounted for in Wisconsin. It’s been on a shelf in my mom’s garage for probably 25 years since her late husband brought it home.
Quick trip through the bead blas cabinet and 4 large number 97’s with SP tops, just have to make the dog bone and the linkage
I've wondered in the past if the left leg of the "H" wasn't a stylized "J" for Jot. I know that that part of the "H" was changed over time.
