Found one of these London Transport made inspection lamps at the weekend. The tank is well and truly knackered as the base plate has dished down to the point where it doesn't sit level any more. I was thinking of replacing the tank with a donor from an X246B as I have plenty of those kicking around. Presumably I would just have to drill a hole in the side and then desolder and resolder the fuel tube. Worth doing do you think, or should I just clean it up and stick it on a shelf?
