THE BAROMETER IS HOUSED IN A RARE UPRIGHT VERSION OF THE DENT SLOPING OAK DISPLAY CASE. This elegant example is comprised of a 4 3/4 barometer with a lacquered brass casing featuring a decorative milled edge. The silvered dial has a scale reading 28 to 31 inches of atmospheric pressure with seven weather indications around the top section. The bottom half of the dial contains a semi-circular spirit thermometer reading from 20 to 120 degrees fahrenheit. The dial has fine engraving throughout and it is signed E.
Dent, Paris London followed by the very low serial number 6037 suggesting an extremely early date of manufacture almost certainly in the 2nd half of the 1840s. The pointer is blue steel and there is an internal brass recording hand adjusted by a raised central brass knob set outside the glass cover. The outer case measures 6 1/2" in width and 6" in height.
It is made from beautifully patinated golden oak with a sloped front and glass viewing port. The hinged front still has the original lock but the key is missing. The fitted interior retains its original blue velvet lining and has a sliding brass retaining bar to secure the ring stem of the barometer in place. This piece is a rare example. I have never seen another Dent barometer in an upright style case like this one.
If preferred, the case could be inverted so that the back becomes the base in which case the look would be like the usual sloping desk model except that the barometer would be upside-down. It is unrestored and in good original condition with some wear to the upper edge of the rear of the oak case and a couple of approximately 2.0cm scratches to the LHS of the glass viewing port. The barometer is in full working condition and readily passes the plastic bag pressure test. The thermometer is fully working wth no air-gaps in the red spirit.
