Werner and Merry Braun sold these Chouinard tube chocks on eBay in 2013. Upon winning the auction the buyer asked Werner to sign the pieces and he obliged. When they finally arrived the new owner was surprised to find Ron Kauk’s name and initials stamped on each piece as well! Besides Werner Braun and Ron Kauk there was also a “RP” stamp on one tube. We invite any comments as to who “RP” might be.
With all the notable ascent these two climbers were, and continue to be, involved in its likely these 1970s vintage tube chocks saw a lot of action on the walls of Yosemite.
