V-TYPE BI-PACK ADAPTOR FOR THE BELL &
HOWELL 2709
Manufacturer
Unknown 1930's - 1940's
Unmarked as to manufacturer, this V-Type Bi-Pack Adaptor for
the Bell & Howell 2709, permitted the use of two 400-foot 35mm motion picture
film magazines for color or process photography.
Some 2-color processes of the late 1920's and early
1930's, such as Multicolor and Cinecolor, involved running (or
overlaying) two strips of film together. Wikipedia
describes the general process as " In bipack color photography for motion
pictures, two strips of black-and-white 35 mm film, running through the
camera emulsion to emulsion, are used to record two regions of the
color spectrum, for the purpose of ultimately printing the images,
in complementary colors, superimposed on one strip of film. The result is
a multicolored projection print that reproduces a useful but limited range of
color by the subtractive color method."
The adaptor's base mounts to the camera, with the film
magazines being attached to each extension resulting in an inverted
"V" formation as shown below, hence the industry designation
"V-Type":

Adaptors identical in concept, were being built in the
early 1930's by the Fearless Camera
Company for their Silent Super-Film
Camera. The Fearless Company's
adaptors (or "adapters" to use their spelling) were much steeper in
design to accommodate the length of their larger 1,000-foot capacity magazines:

Experimentation with multi-color film processes began as
early as 1899. However, it wasn't until the late 1920's and early 1930's that
some of these would become truly commercially viable. Bi-packs by Bell &
Howell and Mitchell came into greater use during this period, with various
multi-color processes continuing to be developed into the late 1940's. With the
introduction of single-strip 35mm motion picture color film by Eastman Kodak in
1950, virtually all 2-color and 3-color processes would disappear by the middle
1950's. Most bi-packs used on Mitchell and Bell & Howell cameras were
vertically stacked, and this is the style almost always seen today:

Although the side-plate cover's grip design on this
V-Type adaptor is similar to those found on Fearless Camera Company's film
magazine lids, and despite the fact that Fearless built their business
manufacturing all sorts of accessories and components for motion picture
cameras by Mitchell, Bell & Howell and others, this unit was probably made
by someone other than Fearless or Bell & Howell.

The unit featured here most closely resembles a V-Type
adaptor for the Bell & Howell 2709, sold by the Hollywood Camera Exchange, 1600 Cahuenga Blvd., Hollywood,
California. Although Hollywood Camera
Exchange had a machine shop, with castings involved in its construction, more
than likely their "HCE Magazine
Adapter" was manufactured (or at least partially manufactured) for
them by someone else. Shown below with
its side-plate removed, Hollywood Camera Exchange's version appeared in one of
their catalogues believed to date to the mid-1930's or early 1940's:

Although the V-Type's construction and appearance might
seem like something more reminiscent of the late 1920's, Hollywood Camera
Exchange's catalogue ad stating that their "V-Type Bipack Adapter is gaining
popularity" suggests the V-Type followed the stacked-style. And, stacked configurations for bi-pack work
were already in use by the late 1920's, as reflected in the December, 1929 ad
for Multicolor Films, Inc. seen below:

Bell & Howell and Mitchell stacked magazine bi-packs
were already in widespread use by the early to mid-1930's, and despite the
V-Type's introduction, stacked magazines would continue to dominate. With no other advertisements for the V-Type
style, no patents found that might cover their designs and no photographs seen
of any V-Type in use, it's difficult to narrow its period of manufacture.
This V-Type
Adaptor is the only physical example of the style that I've ever
encountered. This, together with a lack of information, and that Bell &
Howell and Mitchell bi-packs are seen with some frequency today, these adaptors
apparently never gained a serious following. With Hollywood Camera Exchange's
version priced at $125 (without magazines) when a Bell & Howell 400-foot
bi-pack (two joined magazines) could be purchased for the same amount, I'm
guessing that relatively few were ever made. Of those, most were probably
relegated to some dusty bin, eventually being thrown out or recycled.
A very rare and unique piece of cinematic equipment from Hollywood's Golden Age that I'd like to
know more about.
