Danny, time for me to sign the pledge I think. I'm now seeing everything in threes ;-) Your pic(s) confirm that Mr Chamberlain's piece of paper arrived safely thanks to not one but two slip indicators. You just can't have too much of a good thing!
Perhaps we ex-RAF types should remind ourselves that the RAF Standard Instrument Flying Panel was just that, an RAF one. Other countries seemed to have a more varied idea of what should adorn their instrument panels. I see on the following page to the one you directed me to is a German example of the art, in the Ju 388. They seem to have the offending item attached to the Artificial Horizon (but where is the Turn Indicator?).
Vorsprung Durch Technik!
