Early 20th Century aneroid barometer by Andrew J. Lloyd of Boston. Set on a shield plaque, this aneroid barometer features an unusual rotating dial (rather than a set hand) for indexing barometric pressure movement. This ring is operated by the knob at the bottom of the bezel.
Missing 1 machine screw, some minor wear on the rotating dial, but otherwise in very good operating and overall condition.
