Smiths/ Smiths Empire / Ingersoll / Services CAL 400 history and advise

[luiazazrambo]

Hi *,

I somehow enjoy the CAL 400 movement, probably because it is simple enough for me to understand how it works. Well that's what I say, but took me about 2 months to actually figure out why one of them did not do the tick and the tock. Or did some ticks occasionally. (worn pivot hole in the mainplate for the escape wheel). Now I am trying to put one together with a calendar ring.

1., I would like to know what lubrication does it need for the calendar ring and the associated parts like that little thing marked with red on the picture for holding the ring in position. Does it need anything at all?

2., Different? manufacturers seem to used this CAL 400 movement. Is there any chance there is a service manual for it? Who developed it? Whats the history for these manufacturers? Smith, Ingersoll and Services. Google says Ingersoll had a share in Smithts at one time back in the past. Is there a book or a living person who could tell the story? Andy, you must know everything!  

Best regards,

Lui
