Marty: I think you're getting into a detail that very few know about. I can't tell anything from your photos, but I think I know what you're talking about now. I hate to suggest that something like this is a "Thoroughbred" detail, but that's what comes to mind.
There are 2 ways to approach this. Educate others on the detail, seek out original cars to document the detail and if it's something worthy of a rule update, make a recommendation to have it added. Otherwise, keep the detail in your memory bank and know a little something others don't.
Oh... and try out these gloves sometimes:
