Thanks all - I did look recently on ebay and someone sold a couple of rolls for $15 or so - but they were from the 1950's. I have had problems with some 120 roll film I have here from the 1950's in which the backing paper and the film have fused, so I was a bit reluctant to offer to buy. I had just thought that the information must be available somewhere.

I guess what I need now is the placement of the markings.
