Here we have a very old barograph from English instrument maker Negretti & Zambra of London. Oak case in beautiful condition and the age of the wood is very apparent. This one also has the rarely seen glass lid hinged to the base with a locking latch. Very nice idea as otherwise on other barographs, one needs to be extra careful when removing the lid to grab it firmly to avoid a dropping it! Definitely dates earlier than the 20’s due to bellows/movement design! Has been calibrated and responds perfectly to pressure changes. Clock works as it should and comes with key. Beveled glass is in great condition with no scratches. Comes with 22 original N&Z charts and 28 reproduction weekly charts in inches of Hg and bottle of green ink. A fantastic survivor and a great working antique instrument for any collector! All of the products I sell are tested and calibrated. Using the highest quality calibration standards using a special pressure chamber designed just for this purpose. Not many people have the knowledge or equipment to calibrate these anymore! If an instrument does not perform satisfactorily, I will not sell it! Thank you for looking at this listing and please.
