Thanks Sam,
I wish someone could date them from the mold numbers. The faded shipping labels have zip codes on them, so I guess that dates them at least as 63+ (I think '63 was when they started that)

I did look in an Honest Charley catalog I have form 65 1/2. M&Hs are listed but these are not.
Anyway, they're still as soft and supple as new. Always stored in a cool dark place. I'm not fishing for a buyer because I had no intention of selling them, but I heard from someone I know who is looking for a pair like these for a very special car, but I have no idea what they're worth. (maybe $300.??)
I know a lot of early ones had sizes like 8.50-9.00, or 8.75-9.25, etc, so I wonder if the 7.0/30.5-15 is an earlier or later labelling technique? (I'm guessing later. I think the diameters became important later)
Anyway, thanks. Sure wish I could date them.
