I think Strates bought a Chance bobs from F & B in '77 and it came with a foreman, Bobby Watson.
When I joined in '78 with a couple buddies, I was supposed to go on the Scramber, one buddy went on the diver and another went on the bobs with Bobby Watson. My buddy told Bobby I had moved the bobs for Atlas, and Bobby got me from the Scrambler. I road the train up-county that year and went to work on the bobs like forth man. By (I think) Baltimore, everyone had screwed but me and Bobby. Tear-down, Bobby was pounding out a tub-pin when a chip flew into his eye and be went to the hospital.
I finished tearing down, pulled it to the Harrington and set it up. Bobby ended up losing his eye, and I made foreman and got a nice raise. Did not see Bobby again until we got back to the barn,
I think Strates probably got the bobs, scooter, Rok & Rol and Yo-Yo from F & B at the same time. I'm not sure about the scooter, but all those Chance pieces were old.
Kenny Detty had a "Snowball Express" which was (I think) an old Cortina Bobs with Strates for a while. I think it might have been open-top.
