Metrovick

Metropolitan-Vickers, Metrovick, or Metrovicks, was a British heavy electrical engineering company of the early-to-mid 20th century formerly known as British Westinghouse. Highly diversified, they were particularly well known for their industrial electrical equipment such as generators, steam turbines, switchgear, transformers, electronics and railway traction equipment. Metrovick holds a place in history as the builders of the first commercial transistor computer, the Metrovick 950, and the first British axial-flow jet engine, the Metrovick F.2. Their factory in Trafford Park, Manchester, was for most of the 20th century one of the biggest and most important heavy engineering facilities in Britain and the world. (source Wikipedia)

Metrovick selenium exposure meter, made by Metropolitan Vickers Electrical co. of Manchester, England.  Production date from 1938 until at least 1947. The size is 2 x 2 x 1 inch and weights 6 ounces. The meter dial reads directly exposure times in seconds set at f8 for 23 Scheiner. The calculator disk ranges from 18 ~ 29 Scheiner, f/ 1.5 ~ 32 and 1/1000 ~ 96 seconds. The meter has 2 scales, one 50 times more sensitive than the other, activated by pressing the red button. The exposure time ranges from 1/500 sec to 32 sec divided over both the black and the red scale.


There has been also a model for Leica (1939) with a description "Leica model" on the separate calculator.

Exposure meter for reflected light application Photography and cine. By turning the knob, at the back of the meter on the right side, a band is moved inside the meter. On this band the exposure times and sequential range of numbers corresponding with the numbers close to the needle. Move the band in such a manner that the number the needle is pointing to by measurement, corresponds with the correct film sensitivity scale. Then read the corresponding aperture value and exposure time and set the camera accordingly.
