I have a lot of datasheets on photocells and photomultipliers from RCA - details here

Light-sensitive devices, commonly used for playback of optical film soundtracks, as well as industrial light sensing and measurement.

Manufacturers' Supply Co. IRV4A(4" h.), Cintel 2VA395(4" h.), Osram CMG20(3" h.), CV2134 (1.5" h.) - this had a surprisingly recent date of 1982 on the packaging. Original Advertisments for these devices

Cintel GS17  Osram CM8, Baird VA26, Cintel GS46, Valvo 150AV (2.7" high).

Highly sensitive light detecting devices, used for specialist applications like spectrometry and high-performance image scanners (although semiconductor devices have now replaced them)

Two fairly modern tubes, RCA 4879A, EMI 9656A (both are about 6" long)

EMI 9592G photomultiplier (5" long)

Very cute litte Hamamatsu R1463-03 photomultiplier (1990), with AA battery for scale. Probably from a colour scanner, as it was mounted on a small assembly with two others.

RCA JAN931A (1940s), with data.
