Can anyone enlighten me on these pictured caps. I need one to make a set and I would like to know what the PS stands for.

thanks

P/S is said mean "Performance Specialties." The dealer installed a set of 8-spoke P/S mags on my car when it was new in '72. My caps were the same as yours except the recessed area was painted black (I think - I'd have to go up in the attic and look). Anyway, I have 4 of these caps but also still have the 4 mags and need to keep them together for whenever I put the set up for sale someday ...

From a post about a year ago. Your's are screw in rather than press in but it's the same logo.
