We have been in contact with a gent whose father worked at Dobbie
McInnes in the late 1940's and early 1950's, and was involved in the
design side as well as being assistant works manager.

He is after some information, and I have quoted his first email in full below:

We have a small collection of indicators, and two are the DS1 units. One is in
the 7000's serial number, but the other one was serial 735, nicely below John's
known unit.

I know a few of us have indicators secreted away somewhere, could you check and
see what the type and serial numbers are please?

A typical DS1 unit is at:

Note the McInnes name moulded into the vulcanite at the base. The serial number
is stamped into the top face around the other side of the main nickel-plated
arm, usually in two places.

Any information given is for John's personal use only, and I can give John's
email address to anyone who doesn't want to make their own unit's details
public.

John has also been back to us since then regarding details of the
other units that we hold, including a motorised recorder and the
Schaeffer-Budenberg unit that we bought at the Woodlands swap meet
back in 2003.

Many thanks,

Peter
