Made a mistake in an earlier post. The first picture of the no. 4 O bike is not mine. It is his 175 racer which he went to after he was allowed to move up in displacement. He is a nice man and great to have his history of my bike from the very beginning until now. How unusual is that for an old piece of racing equipment. Street bikes and their history are fairly common but racers most all got trashed at some point.
