The first of the Weston Master series, the type 715, this meter was produced by Sangamo Weston in Enfield, Middlesex and at Newark NJ in 1939. It is the first of the Master series and the first Weston to have an "upright" format.
The photos show meter No F7165, in beautiful condition,bought at a boot fair in Essex UK for £20. It is in an ever-ready case of a type which continued to be used for many years. E2865 was bought at a market in Norfolk for £6 and has a thick leather top-opening case. Both meters work perfectly and are accurate.
These meters are large and heavy by modern standards with a dial that is complex to use. Just compare the dial to that of the Euromasters.
Simon Spaans has some nice pictures of various 715 models here - including the rare Bolex version, and the cine version here.
