Eventually the Pennsy stopped using classification lights altogether (I'm not sure of the transition date, but I believe it was prior to WW2). After that point the front end marker lights could either be mounted on the pilot beam or the smokebox.
Thank you!
I didn't know about the classification lights being discontinued. This explains the red marker lights on some models rather than green.
