Here's a shotfrom the 1978 REI catalog of what was being sold that year.
I also am trying to track down the year for this Stubai rock hammer that I found at the bottom of the Grand Wall in Squamish in 1975. Stubai is in small print on the side.Could possibly be from the earliest of accents as there was no trace of any wood from the handle. Can't find this hammer type by Stubai on the net so far. Maybe someone on here would know.
Also in photo is an old Stubai bolt. I had about 5 of them and it never made it into the rock before it bent. Got them from a store in Vancouver called Teepee sports or something like that that sold mostly european stuff. Got lots of pitons from them too and these scary things.
