Bill,
Lionel DID produce a modern version of the AF Bakers Chocolate tank car with two numbers. As a matter of fact we reviewed it in the digital edition of O Gauge Railroading in Run 311 under the title of, "S Gauge Insights" Neat car. The one we photographed was a production sample and the bulk of the production Bakers Chocolate tank cars have not been released as far as I know. Thought it had to do with the Virus in China at the time.
Will check with a couple of suppliers to see what else I can discover, because, as I write this, Lionel is closed. Heck, I want my two tank cars with different numbers the same way you do.
Hopefully, more information to come.
