I couldn't find any past '61.
Not sure what you mean by "find", but are you searching for "Proto" and/or "Challenger" on Internet Archive? Here is a link to a list of ALL the Proto catalogs on IA/ITCL - where
@macaxis linked the '67 from, sorted by date, in descending order. A very handy site and a very handy sorting feature for any hand tool collector. I see an '88, '82 (Challenger by Proto), '80, and '69 later than the '67.

But I only clicked here to comment on the BET'R GRIP name.
As many collectors know, especially those with a fondness for J.P. Danielson, decades before the name was used by the Proto Tools Division of Pendleton Tool Industries, Inc. (1963-1964), Ingersoll-Rand (1964-1984), and Stanley (1984->) for a line of screwdrivers, it was used by J.P. Danielson for a line of adjustable wrenches. It was TM'ed by J.P. Danielson on October 13, 1936, claiming first use in 1933. When Plomb Tool Company bought J.P. Danielson in October 1946, they acquired the rights to the TM. In 1962, the head honchos at PTI, Inc. cleverly un-retired the name for screwdrivers. Strangely, they filed a new TM, apparently because the original TM was for adjustable wrenches only.
I have talked about this before, but just in case you weren't aware. It's one of the more interesting branding stories in hand tools. In fact, I'd be hard pressed to think of another in which a TM was used for one type of tool and then used decades later for a different type of tool. The neat part is that is still made sense, functionally, and semantically, and was just as catchy, even though the tools had different applications.
