Default Re: Ingersoll watches - war time radio and instruments

Yes, there were several different pocket-watches used with the WWII radios; different watch-makers used different-thickness 'winder' spindles and it's not unusual to find the bakelite pocket-watch holder on a radio has a bit broken out of the spindle-slot in order to accept a watch with a thicker winder-spindle.

As to what Ingersoll may have made during Wartime - well, could be almost anything clockwork - I've seen a "Gent" artillery-ranging calculator (used to set the Az/El of a gun, given range/air-temperature/wind-speed) and a Smiths bomb-trajectory clock used in WWII aircraft.
