I attended The Art of The Motorcycle show in Memphis Tenn. last week. Wonderful show. It will be running through October at the Pyramid, if you are in Memphis. Fantastic display of important bikes from the 1800’s to the present. Here is a link to show information: https://www.wonders.org/motorcycle.htm
There is a bike listed as 1926 Scott Super Squirrel 600 that was restored by Von Dutch for Steve McQueen (I think). Very nice bike in fair condition. I seem to recall that someone posted a set of Von Dutch Scott drawings for sale last year. Purhaps they were related to this bike?
I took some photos with my cell phone that I will try to figure out how to post.
