Timby's Patent two oval dial stick with scalloped/wavy edges. The patent date is November 3 1857, and several barometer makers in the north-east took out licences to manufacture them in varying but similar designs. The patent referred to an iron cistern with a stop cock which allowed the barometer to be transported; unfortunately the joints between the glass and the iron stop cock were not flexible and usually deteriorated over the years. Plase check my other listings under "American Barometers" for more Timby-style barometers.
This barometer is entirely original apart from the tube, which has been replaced.
Maximum dimensions : 38" x 3"
Date : c. 1880
