These cars were built by Pullman for Southern Pacific and have a slightly different window arrangement than the other 4140s. They were 10 roomette, 6 bedroom cars that were found in the consists of the Lark and Cascade. The tail cars for these trains, #4140D, used the same sides with the ends and roof rounded.  At the time of this writing, the SP Historical Society had information on building the HO version of the tail car.
