Hi Jonathan,

Thanks for the Numbers.

Your
1: sn 102024 869 will be a Model 8 and is most likely a Mk III judging by the Date (August 1969).

3: sn 8423 670 as you have said is a Test Set Multirange No 1 High Sensitivity
which was originally known as a Model 9sx (June 1960).

Regarding your no 4, from the description, this will be either a Model 8 Mk I or
an early Mk II. So it will fall somewhere on or between 1951 and 1956.

Sometimes, if your lucky, the original Serial Number was written in Pencil on the back
of the Scaleplate during Repair or replacement, but not always unfortunately.
Study every part of the movement. The Serial No could have been placed anywhere or nowhere.
