At the Davenport Swap Meet last Labor Day Weekend there was Harton, too. I walked by, did the double take and I thought "A Harley cafe racer??". I stopped and started looking at it and was admiring the triple clamps when the owner/builder came over. I looked at the rearsets and looked at him and a Norton frame jumped into my head. His was a sweet scoot, and it was fun talking about his build.
Thanks for posting. Brought back a good memory!
