Pretty certain it is. The Kahler family had a long association with Scot. Robert Senior managed to get Scot to hold an SE race where I thought I remember seeing one of the early frames although not necessarily the one in the pic.
(Coincidentally, it was also the race where me and Mike Hardaway put Scot and Rod over the berm and the OM came us really really mad, but I digress)
I'm pretty certain the guy who started the post, rode for the Finish Line shop. When he mentioned some details about who was getting it, I thought of Bob Sr. but dismissed the thought as the family never had a flair for the dramatic as this appeared to be.
Robert Kahler Jr. was an early #1 plate holder in the Cal-2 district and worked at GT for years and was partly responsible for the mountain bike innovations there.
Must also add that Pat Kahler RIP was also part of the equation and I remember her fondly and very happy the Kahlers have that frame.
