the number is stamped on the back of the wheelcover, along with the CPDD logo, and Made in USA designation.
The wheelcover is an exact match to my G, is 15" and does not have disc brake stamped in it. It could easily be used as a G or H wheelcover (center section is painted black like the H, not red like the G, but has a sort of space capsule shaped splined cast pot metal center with a red dot on the end that protrudes out from the cover. I can't see any number on the cast center piece. Possibly Imperial?
