I just copied this from the flattrack.com forum:
I just got a call from Tim Swain. Someone broke into his shop in Rockford, IL. last night and stole a bunch of stuff including his B50 BSA flattracker that was made up from Gilkeys F-USA frame and the Jimmy Sumner engine. Both the frame and engine are unique in that the frame is a one off and the engine has mods that only I do. I had some pics of that bike but lost them in a puter crash. Please keep your eyes and ears open and any info to;
