the ring has a pair of black index marks (:) next to the black triangle opposite each of the three scales. (The scales are for No.5, No.25 and SM flashlamps.)

c) Align the No.5 index mark with the white dot on the top of the lens barrel. This will line up the other two index marks with the other two white dots. When carefully aligned, press the ring firmly against the lens mount.

To mount the 2-scale ring (for blue flashlamps and daylight color film):

a) Trim off the unmarked sector of the ring with a sharp scissors.
b) Set the lenses again to f/3.5 and note the white dots on the lens barrel.
c) Align the SB index mark opposite the lower right-hand white dot en graved on the barrel of the lens with the f-stops. This will line up the other index mark next to the lower left-hand white dot on the lens barrel. When carefully aligned, press the ring firmly against the lens mount. As you will see, the lens diaphragm numbers (f-stops) are left clearly visible in the space that has been trimmed from the ring, and the lenses are set as usual.

Flash Guide Rings are available for earlier models of the ReaJist camera which have Ilex or Ektar lenses. When requesting this useful accessory you should always mention the type of lenses your camera has.

Remember when using the Flash Cuide Rings or any flashlamp Guide Numbers that they apply only to "average" conditions. For light subjects or rooms with light walls, the lenses should always be closed down to ½ lens stop smaller than the ring or the guide number indicates. For dark subjects or rooms with dark walls, the lenses should be opened up to ½ stop larger than the ring or guide number indicates. A little experience will teach you how to modify the guide number settings.
this certainly looks like a handy device!

26. The Stereo Realist Film Identifier uses the otherwise unexposed picture between frames 1L and 2L to photograph a small card which may be used for name, date, place or other information needed to identify any particular film roll.

27. The Realist sunshades and adapter rings accept the Realist filters and any standard Series V filter as well. They slip over the lenses of the Stereo Realist camera and are held by friction.

nice rings, just don't give one to your girlfriend!
Realist Film Identifier
The Film Identifier is a compact attachment which is easily carried in the camera gadget bag or pocket. There are times when information such as your name, date, place, or film number should be copied right on the stereo roll. This is quickly done by using the Film Identifier as shown in Figure 26. Write out the information on a 15/8x13/8 card and slip it into the Identifier, which will be in proper focus when you use the following directions:

a) After loading the camera (as previously explained) replace the back of the camera.

b) Wind the film until the winding mechanism locks.

c) Wind off two blank exposures as explained in Loading the Stereo Reahst Camera, Step k.

d) At this point place the Film Identifier over the left lens of the camera. This is the lens farthest from the focusing knob. Set the focusing knob at infinity. Expose the card with the special information to be copied onto the film. Exposure is judged according to the available light used.

e) Remove the Identifier and wind off the third blank exposure. You are now ready to take the first picture.

The identification exposure uses the blank frame after the first picture, so that no film is wasted on the roll. When color film is mounted by a laboratory the identification frame will be returned in the box with the other film scraps. You can use the identification frame in your picture filing system, or to identify each roll when a large batch is sent for processing at the same time.

Realist Sunshades
For maximum protection from unwanted reflections, always use the sunshades. These shades are quickly slipped over the lens flanges and do not interfere with the view finder or lens diaphragm settings. The lens
