Default Rank Kalee Type 1742 Wow and Flutter Meter

New member here (from the U.S.). I have a Rank Kalee Type 1742 W&F meter that I'm going to check out for the owner. Unfortunately, I can't find any kind of documentation, such as a user manual, schematic, etc. I understand that this was made a while back (1974?) by Electro Mechanisms, Ltd. in Slough. If anyone has anything they can share, please let me know. Thanks in advance.

I was not aware of the existence of a model 1742 though I am familiar with the 1740 and 1741, as well as the very early model 564.

The 1742 appears to lack the peak wow meter that is very useful when diagnosing problems though a scope display can be used.

Should anyone be interested I have some circuit information on the 564 and 1740 units as well as a pair of each in my loft all sadly unused for the last 40 years.
