Default Remote Unit MR-9B (for Bendix RA-10DB Rx) wiring info wanted

Hi,
Does anyone have a type MR-9B Bendix Remote Control Unit for a Bendix
RA 10DB WW2 aircraft receiver (circa 1942-44) for sale? *I'm restoring
both units as a volunteer for the Canadian Air & Space Museum, Toronto
- Lancaster bomber restoration project, see *http://casmuseum.org/about..shtml
If you don't want to part with it, I could use some good macro
pictures of the wiring as the MR-9B unit we have was butchered
sometime in the last 60 years and I'm trying to rewire the pots and
band switch. *I have the schematic so making some progress but a spare
unit or some pics would help. As many of you know, the RA-10DB
receiver and the MR-9B remote are totally integrated so the Rx can't
be operated stand-alone. *I suppose I could build a complete remote
unit emulator but I'd rather not! *Besides, it won't look right.
BTW, we also have to rebuild the cables. *Does anyone have the right
Canon plugs? *Present plan is to emulate with separate female pin
connectors to the Remote Unit and Rx sockets, two short stubs of
multiway wire and two pairs of modern multiway plugs and sockets. Any
better ideas?
Thanks for all replies,
Cheers,
Roger
PS. Of course, post replies but email any pics to me at "analogdino at
(ta-boy) rogers dot(ty-as-
they) com(e)", suitably decoded. *Visible address is fake for anti-
spam. *Thanks again.


To date, no posts and no email! I have managed to re-connect all the
wires but three.. and I think I'm getting close to them! In a few
days it will be "plug and play", I hope! Also hoping the "new" 65
yeaer old bandswitch motor is not stuck...
Cheers,
Roger
