Locked Southern 390399 "Ortner's 10,000th Rapid Discharge Car" Questions
I've only seen one photo of the 10,000th Rapid Discharge Car, Southern 390399:
In this photo the car appears to be marked with only the large SOUTHERN name and numbers on the side, along with the tagline "Ortner's 10,000th Rapid Discharge Car". This photo is pretty low resolution, but it doesn't appear to show any of the typical data that appears on other cars in the 390xxx series, such as the consolidated stencil, dimensional data or discharge plunger instructions as seen on adjacent car 390423.
A company called Eastern Seaboard Models made a limited run of N scale models of this car many years ago. Their version of the car includes all the data that would typically be found on the other cars in the series. I asked Eastern Seaboard Models if they still had any of the research materials used to create the artwork or if they could put me in touch with the person who prepared the artwork for them. Here is a website showing a couple photos of their model:
So my questions are:
Did this car receive all the data markings at some point after the publicity photo was taken in 1980?
How long did it remain in this paint scheme?
