It is also engraved Compensated' (for temperature). There are 2 scales on the dial both with unusually wide range of measurements. The inner ring reads from 15 to 31 registering the atmospheric pressure in inches.
The outer scale reads from 0 to 20,000 registering the altitude in feet. The front bezel rotates to adjust a fine recording pointer.
The glass is bevelled and appears to be original with no damage. A disc of 5 cm (2") diameter is held in the lid and is also signed "Stanley, London. Mounted on the disc is a circular thermometer with a pear-drop shaped reservoir reading from 0 to 130 degrees Fahrt.
And 0 to 50 degrees cent. The thermometer functions correctly and the silvery fluid is continuous with no air-gaps. It surrounds a tiny brass mounted mother-of-pearl floating compass with a transit lock and covered by bevelled glass. The compass finds north but the lock appears to be stuck in the open position. This could easily be rectified.The disc has the usual tiny crack at it's weak point adjacent to the thermometer bulb. It also has the original cord at the top to aid in pulling the disc from the lid. The barometer is in full working order & passes the plastic bag test. The thermometer is intact, reads correctly and has with no air-gaps in the silvery fluid. The compass regularly finds north but the transit lock is stuck & needs lubricating. Both instruments are held in the original leather covered fitted case which is in quite good condition with reasonable. Wear and what appears to be some old restoration on the sides.
The case snaps shut, the brass button and clasp are both present and working. Internally the case is lined in navy velvet in very good condition. This item is in the category "Antiques\Science/Medicine\Scientific Instruments". The seller is "weatherzone25" and is located in this country: GB.
