Francis Molton, Norwich. c.1800-10.
The early shape mahogany case is outlined with

chequered stringing and has cross grained

veneered sides, another sign of an early wheel

barometer is when the engraved dial is graduated

to 1/10th of an inch rather than 1/100th as on

later dials. 

According to Edwin Banfield (Barometer Makers

And Retailers 1660-1900), Molton was known to

have worked from London, 1790-1810 and was

registered at Dove Lane and St. Lawrence's Steps

in Norwich 1822-30.

Francis Molton. He uniquely developed
the most unusual feature of this barometer, the
method in which the setting hand is operated. The
setting knob, which is at the bottom of the case, is
connected to a geared rod which turns the cogged
setting hand on the dial. Although this was Molton's
own design he only used it on some of his
barometers, many still used the standard method
of positioning the setting hand.
