And another.

Paul Strickland of Onamission kindly provided some images of a C40A identical to my own:

Front view with the massive pendulum bob alongside.

Rear view. Complete in every respect. It looks indistinguishable from my own WT movement.

It would be interesting to discover the serial number of this one. If the owner would care to get in touch I can add the number to my tiny WT database.

Finally, a fascinating collection of parts laid out from a later C40A. Probably post WW2 judging by the pale grey paint, plated parts, the electromagnet coil wrapping and the pressed form of the contact, steady bars.
