The one thing that I could never make work on this bike was the horn. It's a trivial part, but for some reason I just could never get it to honk.
Finally, after all my restorations, all my work, I rewired the horn and <honk>. Only not that kind of honk, the horn sounds like a Canadian Goose - I'm dead serious - I pushed the button and I thought a flock of geese flew overhead or something.

I fiddled with it a bit more and more, figuring that it's just a bunch of rust and spiders, and webs in there keeping it from sounding off like a man - but it never did. My horn sounds like a stinking goose!
