Hi, Can anyone tell me the sensitivity of the regulator on a Eureka clock? The eight legged star wheel has 4 divisions on the scale for each leg, how much does moving it one leg change the rate? I thought that this information might be in one of the sources on Eurekas but I have not been able to find it. I am just getting a derelict Eureka to run again after having to make a replacement train for it after it was destroyed by someone trying to quartz it. Cheers from Neville Michie in Sydney.
