I shouldn't give this turkey it's own webpage, but I'm going to do it just in case someone searches for it. This particular meter was made in Japan and shows up under various badges: Capital, Itzuki Stitz, Allied Impex and Soligor. I have the Soligor version of this thing. The only difference is the badging. If you click on the PDF for the docs, look for the Soligor manual.

This is a bit unusual for a selenium cell: there's a button on it and when you press it, the dial in the meter spins and gives you a reading. Why that, rather than just having a live needle like everyone else, is a mystery to me. You'd think it was a needle lock, except that the dial floats pretty freely when the button isn't pressed.
