[time-nuts] New question slightly off topic.

[v. Bonhorst]

Knowing the knowledge of many members of the list I hope to find an answer
to the following question.
Can somebody help to identify and give hints for documentation for the
following instrument.
Weinschel  1103-5GPA rf power transfer standard.
Basically this is a thermally insulated thermistor mount connected to a
coaxial directional coupler with some means of tuning.
Thank you for any help.
