IKOPHOT Ambient handheld light meter Circa 1960’s

Ikophot was Zeiss/Ikon's name for their hand-held meters; like a lot of companies, they didn't get around to giving them separate model names until later on.

This one looks very much like the DeJur 5, though it's a little smoother around the edges and quite a bit younger (note the ASA dial). They both have that distinct trapezoidal shape and finger notches on the sides to make the dial turn a little easier. This must have been fairly popular, as Zeiss made a couple versions of it with only minor tweaks. Their Ikophot Rapid was the same thing but used a match-needle instead of a scale. There's also a certain resemblance to the Russian Leningrad. I didn't photograph it here but you can see it here: there's a slide-in incident cover for the cell that normally stays in the middle of the case. The early Leningrads both have that same feature.
