Description
Thin card printed with gauges both sides. 4.5 x 3 inches (11.5 x 7.5 cm).
Robert Haswell & Sons, important London based watch and clock tool and material dealers. The premises were bombed in 1940 and it is thought this and other similar material originate from this permanent closure of the business. Examples that still survive are though rarely seen, this having come via the Haswell material saved by Charles Allix.
In good condition with some age darkening to one side.
