1940 -- Distributed by the American Bolex Company and manufactured by Weston, this version of the Weston Model 715 light meter was designed specifically for use with Bolex Cameras. It has markings for 8, 16, 24, 32 and 64 frames per second with the corresponding shutter speeds of Bolex model H cameras.
Incidentally, shutter speed markings for filming at 8fps and 64fps were incorrect (marked 1/16 and 1/60 respectively, where Bolex shutter speeds were 1/20 and 1/80). However, the error that results is less than 1/3rd f-stop difference. The light sensitive cell is located on the back of the meter, along with an auxilliary baffle which can be swung out and locked for lower light conditions. The meter, of course, uses the Weston system of rating film speed.
Frame Counter - External
Before the internal frame counter was included on all Bolex H models, this bakelite accessory allowed the camera to count individual frames during normal operation, hand cranking or rewinding. It operates by attaching to the motor crank shaft, while two counters record incremental movements of single and 50 frames. H-16 and H-8 cameras with a serial number higher than 9400 could accept this external frame counter without modification.  The name plate on the body of the camera was removed and the frame counter was then attached into the holes where the screws held the name plate. The name plate could then be placed onto the side of the counter. Because it protruded from the side, a special winding crank was included to clear the counter.

American Bolex Lens Cleaner
Nothing special here; just a two-ounce glass bottle of lens cleaner by the American Bolex Company. "Removes finger marks, atmospheric scum, grease and grime!", for only 35 cents in 1942. I doubt any of these bottles still exist, but if you happen to have one, I'll gladly buy it from you if the label is still intact. Empty, of course...
Cinelac Film Preserver
Besides distributing Paillard products in the US, the American Bolex Company also marketed their own line of photographic products. Cinelac, Ambol's brand of film preserver, was intended to strengthen perforations and protect the emulsion from scratches. It was often advertised in photography magazines during the 1940s, with the claim, "Used by professional motion picture laboratories and US Government Departments". This article, from 1942, recommends its use on microfilm.
Ambol Projection Screens
This model was available with either a glass beaded screen, or "white-lite" material; the latter, a rubber fabric with a white surface and black backing. It was designed to sit on a table or other flat surface; the case served as a base when the screen was extended. Other models and sizes were available, but most seem to be rebranded versions of earlier Cinea products.
Master Title Kit
The American Bolex Master Title Kit included a 9" x 12" template, designed for spacing and centering title letters, and a set of 222 characters plus 30 periods and commas. After the characters were arranged properly, the template was removed and the title was filmed on a black background. The shot could later be spliced in during editing to help introduce or describe a scene. With the backwind ability of an H Bolex, titles could be superimposed onto a previously filmed scene.
The characters supplied were "Knight Letters", manufactured by H.W. Knight & Son of Seneca Falls, NY. Knight produced a large number of high quality metal titling letters in many unique typefaces during the 1940s and '50s, including blackletter, script and "Broadway" among others. The letters contained in the kit were 5/8" with a serif typeface and were supplied in a partitioned wooden box.
American Bolex/Norwood Light Meter
In 1948, the American Bolex Company began to manufacture and distribute the Norwood Director incident light exposure meter. A brochure from the same year (seen here) advertises the meter at a price of $32.03 US, tax included. After the demise of the American Bolex Company, Mr. Brockway continued to produce the meter and distribute them as the Director Products Corporation; this was later named Brockway Director Corporation and eventually Brockway Camera Corporation before Sekonic bought the rights to the meter.
H Cable Release
Early Bolex Paillard cable releases were available in 10", 18" and 20" lengths. An adapter, fitted to the side release knob, allowed the cable to operate the camera for either single frame or continuous exposures. Later versions, with the same adapter, were only available in lengths of 18" and 40" throughout the 1950s.
L-8 Cable Release
An 18" cable release, with an included adapter, allowed the L-8 to be used without handling the camera. It was available as an accessory in the late 1940s for $4.90. The adapter snaps into position over the release button.
