Thank you for your kind words everybody, I am learning about the car all the time, any Chalmers info is appreciated as I think there is only 3 or 4 Chalmers in the UK and I have not seen any of them. Do you guys have the air start system working ? I have had a new air tank made for safety, but can't get the Kellog pump to work, it turns over when engaged but no compressed air, also when testing the system from the workshop compressor I get a lot of leaking from the air valves when actuated, am I doing something wrong. Layden B, we know wet and damp very well here ! thank you. Andy
