Batteries and Advice on Komamura optical exposure metergreenspun.com : LUSENET : Large format photography : One Thread
I recently acquired a much-used 4x5 system and in the box came an interesting contraption called an Optical Exposure Computer, made by Komamura Photographic Co of Japan during the Punnic Wars, or at least a long time ago.
Two things: First, has anyone used this meter, and with what success?
Second, it needs two batteries. One says "640" on it and the other is larger, and missing.
On the casing is inscribed: A battery: Mallory No.PX-26
B battery: Mallory No.PX-640
Is anyone aware of a modern equivalent of these batteries and where to find them?
Thanks in advance,

Why not ask Horseman. That is where Tosh Komamura works (he owns the company)
