      Today I did what I should have done a year ago. I tried turning the input to the speedometer and it does not like turning. Not surprising, it’s 40 years since it last turned.  Hopefully it is just clagged up wi’ muck.

      This is a 1955 Light 15 Jaeger round clock. First job – remove the newly installed fascia etc and then take out the 2 screws from the back. Easing the works out all goes well for about 5mm and then the trip reset shaft stops moving down its housing and I come to a halt.

      The outer housing of the trip reset appears to be fixed to the casing but, for 5mm, the inner slides easily down with the rest of the workings.

      I am nervous of giving it a gentle shove in case there are bits attached that I need to deal with first.

      Does anyone know how to get the workings out of the case, please?

        A subsidiary question: Is this a chronometric or a magnetic speedometer? It must be about on the cusp between the two, I would think.
