One of the pictures shows it fitted to a Spitfire but I don’t think they were common fit for very long. The Spit usually had the Refelector gunsight I think. I don’t know any facts for sure though.

They are not gyros or desynn motors but Torque Synchro Receivers these will receive a 3 line synchronous transmission from a transmitter somewhere (probably part of a gyro unit) and drive the indicator’s two main pointers but with only just sufficient torque/power to move them, not enough to operate any gearing or other devices.

But it is labelled as 6A/NIV meaning “Not in Vocabulary” – the Vocab being the AP1086 Catalogue of RAF Equipment. So perhaps it is part of the carrier’s equipment rather than an aircraft’s equipment.

Could it be a box/cage for the carrier pigeons!

If you do get anymore detail on it, or indeed on any other types, could I request a copy of it, either on this thread or by PM, please.

Might I suggest that owners of aircraft, cockpits or even maunals try to determine the fire extinguisher types that are (or were) fitted to their aircraft type and then add them to this thread, to form a reference list for us all?
