The User's Review: Three Versions of Petri Shoe Mount Light Meter
These meters are also called as 'Petri Torpedo Light Meter' by some users because of their cool shape. They use light instead of battery to power themselves, and are easy to operate. I believe that they were made in 1960s - 1970s. Their dimension/shape did not changed over the years, but they do have some differences as my three Perti meters tell me. I describe them in an order based on their feature's age I believe.
V1 (left in the images): Has both DIN (11 - 30) and ASA (10 - 800) scales; Shutter speed marked as 1, 2, 4, 8, 15, 30, 60, 125, 250, 500; Has a black Petri logo; No zero screw on the back; Marked as 'Petri Camera Company, Inc. Japan' behind the needle window.
V2 (middle in the images): The same as V1 except no DIN marks on the front ring.
V3 (right in the images): No DIN marks; Has an extra speed scale as 1, 2, 5, 10, 25, 50, 100, 250, 500; A different red logo instead of the black one; The black marks between the needle window and f/speed ring are different from the previous two visions; Has a zero screw on the back, Marked as 'Kuribayashi Camera Industry, inc. Japan'.
