I think it was a commercial paint from Tri-M-ite.

It might produce results by going through their colour sample charts of yesteryear and looking for Pantone colour numbers.

Unfortunately, I no longer have access to the sample books.

Otherwise, there are good paint suppliers who will mix by eye if you have a decent unfaded sample to show them. They'll do liquid in cans, or in aerosols.
