Anglo Exposure Meter Model L-3b, Man. Japan, 1960
At first glance it is unmistakable as a Weston model II; the metal casing is so characteristic. It is very close to the Sekonic LIII Professional, especially considering the needle lock. But there the similarity to either the Weston Universal II or the Sekonic ends.
This unit is functional and well built: The dual-range hinged baffle over the cell is present, but the linked rolling display of units on the meter face isn't. Instead, both the high and low range scales are marked up directly on the face. The calculator dial is of slightly different design, simpler and surprisingly well presented with larger and clearer lettering and numerals, compared to the Weston or Sekonic dials.
Initially, I questioned whether this model was made by Sekonic at all, but having seen and purchased an identical meter with the name 'Sekonic' in place of 'Anglo', I am now sure that this was designed and made by Sekonic as a budget version of their LIII Professional.
I am grateful to David Paschke in the USA for a little more information on this: Anglo Photographics were based in Toronto and traded through the '50s and '60s. They either made or badged several different models of exposure meter with the name 'Anglo', of which the L-3b was one. It is not known how the 'Sekonic' badged L-3b was distributed, nor by whom, nor in which markets.
