PHNB stands for quality and this 100 year plus Barometer was produce in the early 1900’s by a French Company “Pertius-Hulot-Naudet-Barometeres” who made Top Of The Line weather instruments for early Sailors. This Barometers Diaphragm has been Pressure Tested recently and is in Excellent working condition with a few minor signs of natural wear. The face is original and the beveled glass cover has no cracks. Advanced Nautical Equipment co 154 State Street Boston – Made in France markings on the plate and nice polished brass with PHBN marking on back. It weighs in approx 1lb 8 plus or minus a few ounces b/c of my scale, so I believe it is certainly an older model prior to the production of adding zinc to the copper.
