I've just had a look at your thumbnail, and the hand-set appears to be that from a type 'D' instrument. Is that a 'push-to-talk' switch I see? I would suggest, if it is, that it isn't the original hand-set, as there is a cradle-switch for the hand-set mounted directly in front of the magneto generator (an older version than the British version, by the looks of it - has it got two horse-shoe magnets in it?). I 'blew' your circuit up to the best of my ability and the hand-set, shown pictorially, doesn't appear to have a switch fitted.
Our type 'F' (your instrument also?) was meant for 'back-office' duties, and was effectively a more robust desk instrument, hence the use of a cradle-switch. The type 'D' was a 'battlefield' telephone, and could function in any position.
Any chance of a picture of the schematic?
