I am living in Norway, and I have had my Chalmers Six Touring 1922 model for moe than 25 years. It has been running extremely well without any major problems. This year I got i broken differential. That is more serious. Everything is now opened and taken aparte. We could try to reconstruct the broken one, but the best would obviously be if it could be replaced with another differential if it would be possible to find one. Can anyone help me with contact information to persons or organizations that I could talk to in order to get a little further in my enquieries? Per
