Did any mfg'er make a traditional-sized outside braced boxcar?
Crown models? I looked on Ebay with the info that you are looking for and that brand showed up. They had an outside braced PRR box car that looked like some of the postwar starter type cars that Lionel might have had. It looked like it had fixed molded in freight doors with very simple molded in detailing. Seems like Weaver should have made something as well, but I am not sure.
