Otto, you have a 50 model which uses the 47 to 53 wheel. He has a 54 to 59 wheel. May be different, I'm not sure. What I do know is that the 54 6v wheel uses the same contact as the 55 through 59 12v models. One of those contacts I pictured on page 2 of his thread is off of a 12v 59 Panel and the other is from a 12v 57 6400 and my 6v 54 3100 uses the same wheel as the 12v 59 Panel and has the same contact. He has a correct 6v 54 through 12v 59 3100 steering wheel in his 6v 54 3100. He has the correct spring contact minus the plastic insulator in the sw pictured, which is why his horn blew continuously. All he needs is the correct plastic insulator.
