aneroid barometers?

I have 2 broken barometers ie the indicator needles do not move at all, not even by turning the adjustment screw. Presume internal pointer has become detatched from the vacuum box. How can they be mended please? Both barometers are pre War. w1lk1e @tiscali.co.uk

I don’t know your barometers but the ones I know do not have mechanism permanently attached to a vacuum box. Levers system is gently pressed onto the box by pre tensioned hair spring or wave shaped spring. It is possible that your barometers are jammed by dirt (spider silk maybe?) or rust in hinges or pivots. Repairing requires precision of a clock maker. Inspect first with good light and strong magnifying glass. Professional help:
