The Holdsworth trike we have been discussing has Williams cranks stamped with AJ which I am told stands for 1947. The cranks are original. The wheels are 32 hole 27x1.25 Dunlop Specials with an Airlight front hub. The frame is of lugless construction and was resprayed by Holdsworth. I have some pictures of it. If I can figure out how to post them some where I will do so. I could also try forwarding them to anyone who is interested. I need to learn how to do that anyway.
