I just picked up a very nice 1939 Lionel 225E freight set which runs great. The only issue I noticed was that the headlight was not working. When I opened up the hinged boiler front there was no bulb, no bulb socket, or wire. I looked at Olsen's part diagram for the 225E but it does not list a light bracket/socket. After some more web browsing it appears that it uses a 78-78 brass screw type lamp socket but it seems like there must be some sort of bracket that attaches the socket to the boiler. If I could see a picture or a 225E with the boiler front open it may solve the mystery. Thanks!
