Jonas Barber Jnr (b.c.1718-20) was one of the finest clockmakers in the North West.
Circa 1748 he began numbering his clocks, engraving the serial number on the movement frontplate (and sometimes with the date of manufacture alongside). His clocks can therefore be dated using these numbers. Barber numbered to the mid 1400s until 1800 when his successor (and former journeyman) Henry Philipson continued the system.
