This is a Dynopower unit supplied under the lend lease scheme by the US hence it has both US and Air ministry plates. The Dyno units are extremely rare items, we have the complete set up for the TR 5043 listed here.


 Spitfire Identification friend or foe contol box (IFF)  (pg3 rad)

Here is an extremely hard to find IFF control box in fact this is the only one I have ever seen. Used in the Spitfire as well as other RAF wartime aircraft.

1 Jan 1940 - The RAF introduces Identification Friend or Foe (IFF) signals to help identify Bomber, Coastal and Fighter Command aircraft on radar screens.
An IFF system acts as a radio transmitter and receiver. It sends out continual radio signals made up of coded pulses. A friendly IFF system will recognize these codes when it receives them and will transmit further coded pulses which identify the aircraft to the interrogating IFF set.

 Spitfire Identification friend or foe receiver R 3109 (IFF)  (pg3 rad)

This is a IFF friend or foe receiver this particular version is the R3109 so likely to have been used on later mark Spitfire and of course bombers. Outwardly the same unit as the R3108 just different voltages. Rare in the extreme the only one of these ever offered for sale that I have seen.

Not sure about dates but most likely around 1942/43 as the following extract talks about USAAF/RAF intercommunications.

1 Jan 1940 - The RAF introduces Identification Friend or Foe (IFF) signals to help identify Bomber, Coastal and Fighter Command aircraft on radar screens.
An IFF system acts as a radio transmitter and receiver. It sends out continual radio signals made up of coded pulses. A friendly IFF system will recognize these codes when it receives them and will transmit further coded pulses which identify the aircraft to the interrogating IFF set. 


FF Mark II was developed to cope with the additional frequency bands of newer radars, and covered these in three swept ranges, including the original IFF MK I band.


However, radars were advancing at such a rate that IFF MK II soon did not cover the frequencies in use so variations were produced for other radar bands, such as the IFF MK IIG and MK IIN which were British sets for UK radars, and the USA SCR-535 (ABE) and SCR-535-A which worked with the early US Army radars such as the SCR-268, SCR-270, SCR-271 and SCR-516. The US Navy ABE and ABK sets worked with naval radars.


The IFF MK II was designed to allow switching between any one of 6 different coded responses, usually specified for various types of mission. However, in practice it proved difficult to distinguish one echo from another so generally only position 1 (or A) was used, whilst the longest, widest response position was used universally as a distress signal.


In order to respond to the growing number of radars in service the aircraft or ship often had to carry multiple IFF units.

The services recognised that with the proliferation of radar and other equipment there was a need for a distinct frequency band for IFF with a common equipment specification. They chose the 157-187 Mhz band.




The remote contactor and the IFF clockwork control that works with this system is available in the instruments section link here

Battle of Britain Spitfire radio TR1133 (pg3 rad)


Its an original TR1133. This radio was only fitted to Spitfire's and Hurricane's for a short period during the Battle of Britain. It was replaced soon after by the TR 1143 and  TR 5043. I am also including the rare Dyno that power's this set. The dyno and radio appears to be in good order internally and has a 12volt input as it should be with early Fighters.

Michael Clarke has this to say about the TR 1133.


Some time during the Battle of Britain the RAF introduced a VHF set into the Spitfire. This was the TR1133. When a VHF set was fitted the aerial was removed leaving the aerial mast alone to transmit and receive signals.

I have never seen a TR1133, or a picture of one, but I believe they used the push-button type controller with a ‘Jones Plug’ type connector at the back. In fact I think ‘Jones’ connectors were used throughout the installation. 

I understand that Spitfire Mod 385 introduced the TR1143 in lieu of the TR1133. This was in the middle of 1941.

B17 Trailing Aerial (pg3 rad)

Unusual US heavy bomber item this - a reel for the trailing aerial for the B-17 and B-24.  The wire is stainless steel and the reel is in excellent condition.


Heavy Bomber radio/radar selector (pg3 rad)

This unit is very similar in design to the Spitfire radio tuner but with a double bank of switches. Its reference number lists it as a radio/radar selector. The radios in heavy bombers were tuned manually by the radio operator so this is probably for radar selection.

Spitfire Beam approach aerial 2 (pg3 rad)

Spitfire Beam approach aerial (pg3 rad)

This aerial is a for the Beam Approach it was used on Spitfires and no doubt other aircraft of the period too. I think the beam approach was used as an option with the TR1133 or TR1143 setup - at least the Spitfire Mk V manual seems to illustrate this. In good condition.

Lancaster J type switch (pg3 rad)

This is a big chunky switch box mounted in the radio operators position on the Lancaster and other heavy RAF wartime Bombers. It s used to select different aerials used on the aircraft such as the DF loop and trailing aerial. In good original condition switch moves as it should.

Fairey Firefly

Sea Mosquito/Firefly Radio Selector (pg3 rad)

This item is the pilots control for the AN/APX2 IFF transponder set. They would have been standard  fit for a variety of aircraft during and post war, both British and American.  Used in the Grumman Avenger, Douglas F3D Skynight for certain, and probably most late war bombers (one reference to the its use on B17's, but I have yet to see any radio fit diagrams). In the UK I have found explicit references to the Sea Mosquito and Fairly Firefly. During the war these sets were both very sensitive and being rapidly developed, hence there is little readily available literature on them. Your component is the radio operators control, there was also a simpler unit for the pilot to use (often the only one fitted in single seat aircraft - see attached image).
 Information kindly supplied by Robert Broughton.

USAF Dolls Eye (pg3 rad)


This is a navigation aid fitted to wartime USAF aircraft.



The Gibson Girl Emergency Transmitter was included with abandon ship provisions in life rafts. It was also packaged with a parachute so it could be dropped to survivors in the water. The Gibson Girl is operated by holding it between the knees while cranking the internal generator by hand. It can be set to automatically transmit an SOS signal or manual keying can be used to send a message.

Gibson Girl (pg3 rad)

Radio Set SCR-578 is a hand powered emergency transmitter ruggedly designed for use in a life raft or small boat. Use of the Gibson Girl enabled rescue crews to locate survivors of ship or aircraft emergencies. The SCR-578 and its accessories were bright yellow-orange in colour and the unit would float if placed in the water.

This one has its carry strap but is missing the winder located in the back see picture left, its is also missing the knob on the front that closes the door that houses the aerial cable see picture top left. Still a nice item should not be to hard to make a winding handle we could make it for you if required. Will find a suitable period knob to be included in the sale for the door.


Original Gibson Girl box kite (pg3 rad)

Original Gibson Girl box kite used for deploying the radio areal. Its not in great condition with some holes and corrosion marks but still a nice item and quite sturdy.

Information on the Kites can be found here

TRII96 and RII47 (pg3 radio)

R1196 and R1147 

The Seafire also had different and additional R/T sets presumably to allow ship-air communications and perhaps also some form of homing device. These were the TR1196 and R1147 respectively.
