Bill, I have a shot of WHIX 70000 (from the GNRHS 1999 calendar)As I was copying photos I was startled by a shot I have of
that shows the weird ribs, but also a good 1970's photo of WHIX
70635 that really shows the ribs well -- and they are UNUSUAL to
say the least. On the upper panel the ribs are equally spaced but
because the topmost one is straight along its bottom edge, it
almost looks like a 1/2/3 rib arrangement.
I also have a beautiful shot of WHIX 70290. I'll send these to
you and Jeff and you can decide...
