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 authenticity. This is one of the initial barometers issued by the RNLI to masters and owners of fishing vessels at the subsidised rate of eleven shillings and sixpence, a third of the retail price. Both Dollond and Negretti & Zambra manufactured these marine barometers which were issued from August 1882 onwards, and by November 1883 over 1,200 applications for the Fisherman’s Aneroid Barometer had been received. The RNLI then agreed to extend the same subsidised price to a number of masters and owners of coasters under 100 tons.

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.
