Try the GenRad Group on Yahoo. Some GR design engineers are in that group.

Also, there is a General Radio Historical Society with an extensive manual
archive.

> I am in the early stage of writing a history of the General Radio model
> 275 crystal (piezoelectric) oscillator. I have one complete 275, and parts
> to a second.  The 275 was the first commercially available crystal
> oscillator.  I hope to restore both 275s to operation.  The paper will
> also cover the model 375 station monitor which followed the 275 and used
> the same oscillator.  I have most of a 375, which I will soon begin
> restoration.  I am interested in any pieces of hardware, including models
> 276 and 376 Quartz Plates, and any documentation (or copies thereof)
> including the relevant portions of the General Radio E and F catalogs.
