Here is a quality reproduction of the piece fitted in the RHS of the Spitfire cockpit, if the aircraft crash landed in Enemy territory the Pilot would push the three buttons , this would set off a timer that would destroy the entire IFF system. The push buttons and shrouds needed to complete this piece are listed in the electrical section. If need a unit made up ready to fit please contact me.

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.

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.

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.

TR1133

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.

This is a radio tuner for the early type radio sets as fitted to Seafires. It tunes to radio manually by means of a flexible cable drive. It was fitted to the LHS of the cockpit. Its in relic condition with part of the airframe and a cockpit lamp attached. The handle is seized and will not turn. Great display piece.

Radio filter fitted to Thunderbolts. See nos 2 under in situ in P47

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.

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

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).

Sea Mosquito

This is a navigation aid fitted to wartime USAF aircraft.

This original phonetic alphabet instruction plate is in superb condition, I have never seen one of these before.

See this in pilot equipment link

The Dyno

See reference section for more details on radios and transmitters.

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.
