Thanks for the links HH56, I hadn't seen that second thread. The 29-31 parts look very similar to the 33, as far as the hand controls go, except mine doesn't have that spring on top. Looking carefully at the 33-36 parts book diagram it's tough to tell, but it doesn't look like there's a spring in that location. It does look like there's a spring directly under the horn button though. I'm also trying to determine whether the three screws that hold the horn button to the brass "fingers" need to be isolated from them. I don't see how it wouldn't constantly ground out without those fasteners being isolated.
