I’m trying to locate prototype information/photos of the National Car Company refrigerator cars with SNX reporting marks. From the 1953 ORER, the private car owner for these cars was Stadler’s Packing Company in Columbus, IN. I’ve attached a photo of the car that 5th Avenue Car Shops made available, and it shows that the car was to be returned when empty to the PRR in Columbus, IN. Thanks in advance for any info/photos that can be used to upgrade this Accurail car.
