Now the bit that interests me about this instrument. The supplier code is shown as S on both of these instruments. I have S as being the supplier code for Smith and Sons.
I will need more evident for, if the code was also used by Smiths.

Anyway powerandpassion you have given me another supplier code to add to my database on then (read, a short list that I would like to lengthen).

Thank you Aircraft Clocks and Bob, much appreciated.
