For those who might be interested, I checked the cab numbers of the PRR engines to see when they were retired. All made it to post-WWII so either configuration would work for those numbers. In the catalog, the pictures of 1343 and 1627 are post-WWII, the other three are pre-1946. Keep in mind some pre-1946 configured engines remained that way to the end of PRR steam in 1957, but I can't find that information.
Lehigh and New England bought four in 1941, so their engines would be pre-WWII and the catalog picture looks correct. Not sure what mods they did after they bought them.
Detroit, Toledo, and Ironton bought their two in 1948, so again the catalog picture is correct.
The Santa Fe bought their three in 1945 so the dynamo is correct but I don't see any marker lights in the catalog picture.
Looks like Lionel did a good job on their research for these.
