Hi folks, As introduction, I'm Bob Lucas and new to the SL-SF group. I'm Publications Editor for the AC&Y Historical Society (and Frisco fan) and also author of the recent Morning Sun book covering the AC&Y-A&BB. I'm seeking information on the SL-SF 152,000 series auto cars built in June 1930 by General American for a comprehensive historical article on these interesting freight cars. Fast forward to 1959... two-hundred ex-Frisco auto cars were reconditioned and leased by the AC&Y for tire and wheel rim traffic. I did locate general arrangement diagrams/specifications for three sub-groups, two of which appear to have been modified at some date with Evans Auto Loaders. I would be most appreciative for any additional information and/or photos of these cars.
