Revue Studio/Norwood Director
I have to say first, that this is by far the most accurate exposure meter with a Selenium cell I've hold in my hands. The needle moves quickly and the results are reliably reproducible. This exposure meter belongs to the great family of the "Norwood Director" meters, which were a milestone in exposure metering.
The first electric meters in the early 1930ties metered the light reflected by the subject. The method of metering the incident light was already known, but it got more practicable after its refining by Donald Norwood. He developed the characteristic translucent hemisphere (he called it "Photosphere"), had it patented in 1940. Around the same time the cinematographer Karl Freund founded the company Photo Research to produce exposure meters, finally also the "Norwood Director". They have a very particular look: a "body" with scale and a rotatable "head" with the white hemisphere. At first the calculator dial was on the rear side, later it was shifted to the front. That appearance was kept for decades and exist in countless variations, and as far I know you can find it even today.
Later the Brockway family, owner of American Bolex, took over the marketing of the Norwood Director and offered new designs. That's the reason why some meters are labeled with "Brockway".
In 1957 also the Japanese company Sekonic started to produce Norwood Directors, the first model was actually labeled with Brockway, certainly because the name was already well introduced in Hollywood. But already the second, nearly identical one was called "Sekonic Studio S", in Japan "L-28", following the usual Sekonic name scheme.
Now we are at the Revue Studio, it is identical to the Sekonic Studio S. Okay, not exactly: since Revue was a trademark of the German mail-order house Quelle, the film speed is given in DIN and not in ASA.
The Revue Studio/Sekonic Studio S is very versatile, the amount of functions can be a bit difficult to control. Basically it can be used conventionally: set the film speed, transfer the value indicated by the needle to the calculator dial and read out your shutter speed/f-stop combination. In addition the meter has a "direct read" feature: For certain film speed/shutter speed combinations (e.g. DIN 24, 1/60 s) you can read out the correct f-stop directly from the scale. For other combinations you can insert 3 different "slides" - these little black plates in the picture - between Photosphere and metering cell. Then you have DIN 19 and 1/200 s for example. Slide #3 has gone, somehow. Unfortunately the f-stop scale, red numbers from f/1 to f/32, is covered by the dial in my picture.
And of course it can happen, that you want to meter the reflecting light instead of the incident one. Then you can replace the Photosphere with the "Photogrid", that round sieve you can see in the foreground.
Sekonic also provided a third attachment, called "Photodisk" and also missing here. It is like the Photosphere, but flat. With it you could meter the illuminance in foot candles. Useful for determine the contrast of light in a studio, e.g.
You can also determine f-stops for filming ("cine"), exposure values EV (here: LVS), special numbers for Polaroid film used in those days. "Those days" mean around 1966, then that device was sold for 79,- Deutsche Mark.
What I miss is a button to hold the needle in place, for more convenience. That feature can be found on some later models.
You can find comprehensive articles on the net, e.g. by Douglas A. Kerr or James Ollinger.

My first attempt at toning with selenium
It just goes to show what you lose when you scan a print. Three identical prints from the same neg with (L-R), no toning, selenium 1+9 for 1.5 mins, selenium 1+9 for 2.5 mins. There's a definite deepening of the darker tones across the three, but a lot of the subtlety is lost.
All on Ilford multigrade warmtone RC paper using Ilford warmtone dev.
Added selenium tone in Lightroom; I think I'm starting to like this one more than the original; post up if you have an opinion :)
A nice ragged old set of shutters i spotted whilst i was in Venice. I took this with
Edward Weston's Potato Cellar Shot in mind as well as my AS Level Photography Project, looking at texture in architecture. Made B&W in Lightroom, Dodged, Burned and added a Cooling Filter (LBB) to get a Selenium tone feel in Photoshop CS4
Ilford Warmtone in Berg Selenium from Ilford Delta 100 in Canon 100mm f/2.8, downtown Guelph.
I wish the digital camera could properly capture the selenium tones but you have to see this one in person. It is 11x14" so too big for my flatbed scanner though perhaps I'll try scanning a portion to see if it can pick up the subtle color.
