Here is a recent estate find. This is a Rare Antique Surveying Aneroid Compensated Barometer, Made by Negretti & Zambra Aylesbury 1451, Made in England. 5 in Diameter, and is in Good Cosmetic Condition!!! It appears to be working, but has not been Calibrated. This Might Be What You have Been Looking For!!! What you see pictured is what is included!
