Jaeger-LeCoultre Smiths M1 car clock

[OzTickTock]

Hello experts. I have a 1930s smiths M1 car clock. It seems to be unusual, as instead of folding out or removing the clock to wind, it stays in the dash, and you wind it with the dial. There is a little knob on the side to change the action of the dial to set the time. The most unusual thing about the clock is that the dial is approximately 55mm across, which is smaller than other smiths m1 clocks. Unfortunately, the winding dial is missing, and the balance wheel broken. Can anyone help me source information or parts please. Thank you
