I have a GR 1123A not fully restored yet. Performance of that 815B looks
impressive!

Subject: [time-nuts] General Radio frequency standard question
Some of you know I spend as much time looking backward as looking forward:
both ends of the precision time envelope are extremely interesting -- from
chronometers and tuning forks -- to cesium clocks and masers.
In particular I trying to restore and power up several old NL (Norrman
Laboratories) and GR (General Radio) pre-quartz frequency standards/clocks
from the 1930's. Can someone tell me if there's an active GenRad user
group, web-forum, or mailing list on the web? In spite of a heavy shelf of
General Radio Experimenter magazines, GR catalogs and GR manuals, I could
use some help.
Replies on- or off-list are ok.
For those of you new to the 20th century history of time & frequency see
mouth-watering specimens like:
