a couple of years ago, it was in a poor state, with sections of the wiring missing, among other things. The wiring has been mostly repaired, but I've been procrastinating on sorting out the ignition barrel removal, as the ignition key is missing. So, today was the day. As this is my first bus project, I did some reading and viewing some YouTube videos. After two hours of frustrated fiddling, the barrel managed to come out. I'll go to a locksmith tomorrow to have a new key cut.
A previous owner probably drilled a hole in the housing to facilitate removal of the barrel, but it wasn't useful to me. At first I tried a brazing rod to push into the hole on the side of the barrel housing, but it was too weak. I ended up making a hook out of a stiff chrome spring, which did the trick.
