Boatanchor Receiver - IMRC - UK Vintage Radio Repair and Restoration Discussion Forum

SeanStevens · 19th Nov 2010, 2:16 pm

An aquantance has found a huge radio receiver he was told come from a Cunard Liner!

The thing has no model number, but is 2.5ft by 1ft deep x 1.5 ft and looks to have been rack mounted (handles on the front)

It has IF Gain
DFO Pitch
RF Gain
Band selector
Tuning (Fine and Normal) in one knob
Valve Check 1-10
Selectivity (Wide, Narrow, Very Narrow)
and tons of sockets

Any idea what it is? The only markings it has is IMRC printed in a red circle. Photographs (possibly) to follow after the weekend.

Do we have a resident Boatanchor expert onboard Captain?

International Marine Radio Company.
(Part of Marconi, if my memory is correct.)

If you go to http://www.eddystoneusergroup.org.uk/ and look down the left hand side of the home page and click on the 'QRG' link and look in 'Post War Sets' page 9, you will see the Eddystone S700 also known as the IMR.54 which was used on Cunard liners.

If it is the IMR 54 then it was designed under contract by Eddystone to IMRC in 1952 who where a subsidiary of STC and competitors of Marconi Marine. Eddystone made the first 205 then fell out over the contract price with IMRC who took the design and jigs and started to make their own. Eddystone made one of these for the directors board room and called it the S700. The IMR54 was used on RMS Queen Mary

Wow, that document covers lots of models. Thanks for the link and info.

They are beasts. If anybody collects these things I can put them in touch with a guy who has one of these monsters. I'm going to see a photograph of it next weekend, that might help me identify the model, but it doesn't look promising as there are not identification plates on it apparently.
