[Dreaming 60's]

I posted this on CF and didn't get much response, as expected. But, I was hoping since we have some seasoned members here who are MIA from the CF, maybe they could shed a little light on my question.

I've pulled and getting ready to sell my Kelsey Hayes KO wheels off my 66. Three wheels have definite 66 dates stamped into them, but one has an odd B12-21 date that doesn't fit into any dating stamps I've seen. It has the KH logo stamped/cast into it, so I know it's real, but certainly raises questions.

Looking for any ideas, experiences, theories or ?
