Hello everyone trainfam here,
about a week ago I was repairing a Lionel standard gauge 38. All was going well and nothing seemed out of the ordinary. That was until today when I was cleaning up my wheels. I noticed that one of the wheels had some odd marks on it. It seemed like the rim Of one of the wheels had been engraved in. It looks like the rim has “5-L-4U” engraved on it. Take a look:
I’ve never seen anything like this before. Does anyone have a idea about what it could mean?
