This is a very good 150-year-old mercurial banjo barometer for restoration. It is the tulip style made in england between 1850 and 1880, i estimate. These are very hard to find now; i found this one over 20 years ago. You can see the price the dealer had on it; i didn’t pay that!
The top hygrometer is completely missing, but the very valuable thermometer is complete. The mercury tube is missing but the rest of the operating parts are there. This is a great antique barometer which you can restore at a reasonable cost and enjoy for years to come. Optional/additional mercury tube: the original mercury tube was broken but i can provide you with a partially filled tube and enough mercury to fill it for $55. I will provide a filled tube for $95.
I would pack these carefully within the case but i cannot guarantee their safe arrival. You should enjoy bring this great barometer back to fine condition.
