Here are some pictures of my new light meter from the 1960s.

It's a Weston Master V. It has a selenuim cell which means no batteries. It's not as sensitive as the Luna Pro that I lost and found but I like using it. It just feels good and works great. It is basically still in production as the Euromaster II. Here are a couple of sites on these classic meters:

Weston Master & Euromaster.

The backside is where the selenium cell is that reads the light. The meter has two scales. For bright light the cell is covered.

And uncovered in low light.

The other pouch has the invercone which turns the reflective Weston into one of the best incident meters. I've found the incident meter to be handy for studio stuff. The Luna Pro has incident capabilities but I've never felt that it was really comfortable being an incident meter. This one is. Now I have two meters that are guaranteed to give different readings!
