Foley,

It is still set up so I will take some pictures. I too worked in a service station in the 60s, all through high school.

I used to repair tires back then and I worked on split rims doing repairs on them. The rule was always put the wheel under the rack when you inflated it, banging on the outside rim when doing so. These rims are basically safer than the style with the split on the very outside of the bead. Since this locking devise is lower in the rim and the outer bead ring moves over a portion of it the part that could fly off is partially covered.
