Unfortunately it appears that the mercury thermometer tube is non functional and will need to be replaced. Please check pictures for more details.. The item is in it's original condition and looks in fantastic cosmetic shape. (I have no experience of these instruments so can't really comment on functionality etc)I haven't cleaned or polished the barometer but it will definitely come up a treat with a little bit of TLC.Collection only, due to being a very fragile item. This item is in the category "Antiques\Science/Medicine\Scientific Instruments". The seller is "2011tezza222" and is located in this country: GB. This item can be shipped to United Kingdom.
