Does anyone know if the RCAF maintains a museum anywhere dedicated to this equipment, or do they have a Directorate of History anywhere that would have references to equipment used/manuals for same?

I have an ex-RCAF Communications Receiver, which RCA ID'd as an AR88LF for the Army during World War II. The identical receiver in RCAF use was known as the GR-17 Communications Receiver. This set was built exclusively by RCA Canada in their Montreal plant during the war. The set would have been issued with an RCA published manual for the AR88LF, but apparently the RCAF also produced their own manual for the same set. This RCAF Manual was identified as:

EO 35BB-5GR-17-x

GENERAL PURPOSE COMMUNICATIONS RECEIVER INSTRUCTIONS


I haven't a clue how to decode the alphanumeric reference other than it contains the GR-17 ID and the last two characters '-x' would relate to the version/edition.

I have only seen a few very old thermal transfer onion skin photocopy pages from this manual. It would appear to be an 8.5" x 11" looseleaf format that included some update pages from 10 April 1961 and 23 May 1961 coded EO 35BB-5GR-17-7.

The RCAF used some of these sets in an Intercept Monitoring Station close to the Whitehorse Airport during the war and probably into the Cold War at some point.
