Conventional single 2” capsule driven movement tensioned on C spring and mounted on a wooden block (characteristic of early instruments). Zinc drum form case with fixings at 12 and 6 o’clock. Calibration port to verso.

Condition: The subject of an extensive service and conservation. Tested and calibrated under laboratory conditions, see performance chart below. The dial undamaged but with normal crazing to the glaze, the markings clear and having good density.

The glass and bezel a contemporary or period replacement.

Comments: The important thing here is that this instrument was “Issued” by the RNLI and not “As Issued.” This does make a difference to value and in some respects authenticity. This is one of the initial barometers issued by the RNLI to fishermen at the subsidised rate of five shillings, each barometer costing the RNLI eleven shillings and sixpence. Both Dollond and Negretti & Zambra manufactured these marine barometers. Generally this instrument presents well, being in much above average condition – the dials are quite fragile and many are cracked or repaired.

This RNLI marine barometer is a collector’s piece.

Dimensions: 6¼” diameter x 2¾” deep
