Can anyone give me further information about these two cars?  SLSF 152203 was a 40' double sheathed end door auto loader in series SLSF 152000-152228.  It was photographed unloading a DUKW onto a Boston & Albany flat at the San Francisco Port of Embarkation during WWII.  I wrote about the book, Gateway to Victory, back in 2015 https://northbaylines.blogspot.com/2015/12/san-francisco-port-of-embarkation-sfpoe.html

I've looked through the Sunshine all time list and associated flyers and came up with earlier and later cars, but not the 152000 series. 

 

The B&A flat has to be one of the 186 cars remaining in the 16000-16399 series.  The build date and capacity eliminate the other B&A flats listed in the Jan 45 ORER.  The Canada Southern Railway website lists the cars as members of Lot 300-F built in 1912.  The 4-13 build date in the photo is consistent with an extended delivery from a late 1912 order. 

 

I would like to model both of these cars.
