the dail looks strange ?
I did not know that this reference was carried into the 1960's. When did they put the numbers on the outside of the case? I'd like to see the inside of the case back.
I'm guessing your question is related to such an older ref. being made in the late 1960s AND the serial # being on thr outside for such an old ref., even if it was made in the late 60s?
A good question.
i didnot see your ref. 7592 with the serial number on the outside of the case back:
i see it. thank you
