Fisher Sports Catalog
Dating this catalog is a little tricky. Some retailers used to intentionally leave dates off of their catalogs so the issue could be considered “current” for as long as possible.
Here are my thoughts:
Several guidebooks are mentioned on page 52 as being “reprinted in 1967” and the larger size Chouinard Bong pitons shown have no lightening holes (that happened around 1970ish) and the Knifeblades shown only have a clip-in hole (second hole added in 1971 I think).
I guessing this to be a 1968/69 catalog based on those observations.
