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.
This is a very robust meter, has lasted 75-years and still going strong.
Condition: Very good with no damage.
Works perfectly and seems accurate.
