Acro Model C
A forgotten 1940s Bakelite camera with a working rangefinder, found in a dusty box. This is the Acro that almost nobody remembers.
Overview
"Acro Model C" is a ghost. The name keeps turning up in searches and points nowhere real. Catalogs, collector databases and ads from 1940 all say the same thing: the camera people mean is the Acro Model R, also labeled on its original box as the Model R Candid Camera. It's a half-frame 3x4 cm rangefinder for 127 film, made by Acro Scientific Products Co. of Chicago around 1940. The "C" looks like a persistent typo or misattribution, possibly confused with scissors, red dot sights, or just wishful thinking in online listings.
In 1940 most budget cameras were basic box types or viewfinders. The Acro Model R came with a split-image rangefinder, an extinction meter, and a self-cocking shutter, all in a Bakelite body the size of a small lunchbox. It was the only 127-film rangefinder on the American market at the time. It held that title for nearly two decades, until the Revere Eye-Matic EE showed up in the late 1950s. No competition for almost twenty years.
It wasn't built from scratch. The design borrows heavily from other Chicago-made Bakelite cameras of the era, especially the Detrola and Falcon lines. The body, helicoid, lens, and shutter setup are all cut from the same mold. Collectors call this group the "Chicago Cluster," a loose network of brands that shared tooling and parts. The Model R added one crucial upgrade: the rangefinder. The little metal housing on top, finished in aluminum, contains the split-image rangefinder and a reverse-Galilean viewfinder, plus the extinction meter and a calculator dial to interpret the meter reading. That's a lot of gadgetry for a $15 camera (or $18.50 with the faster f/3.5 lens).

Key Features
The Rangefinder That Set It Apart
Putting a rangefinder on a budget camera in 1940 was bold. Most 127 cameras were simple viewfinders, if they had any aiming aid at all. The Model R's split-image rangefinder, mounted in a removable aluminum housing on top, was a serious upgrade. It's uncoupled, so you focus manually using the distance scale on the lens. The rangefinder itself is reportedly bright and effective. Owners call it "amazing for 1940." It gave amateur photographers a real tool for sharp images, especially in low light or with moving subjects.
Bakelite Body with Metal Guts
The body is molded Bakelite, labeled TRCO (for The Richardson Company, a plastics molder). The lens and shutter unit are mounted on a metal plate screwed to the front, and the rangefinder housing is all metal. This hybrid construction was common in the Chicago Cluster cameras - cheap to produce, but sturdy enough for real use. The red window cover is a rotating disc, which keeps light off the film during advance.
Self-Cocking Shutter and Extinction Meter
The pre-war size 0 Alphax Jr. shutter is everset, meaning it self-cocks when you advance the film. You wouldn't expect that at this price. Speeds run from 1/25 to 1/200 second, plus Bulb and Time modes. The extinction meter on top works on a simple principle: you look through it, and a small patch of light fades as you adjust the aperture and shutter speed. Match that to the calculator dial and you have your exposure. It's primitive by today's standards, but in 1940 it was a selling point for the "economical precision camera" crowd.
Historical Context
The Acro Model R arrived in 1940 in a crowded field of nearly identical Bakelite cameras. The American market already had the Falcon series from Utility Manufacturing and the Detrola line (Models G, H, and K), both offering similar 3x4 cm viewfinder cameras. Acro added the rangefinder, which neither Falcon nor Detrola offered. It worked: Sears picked up the camera for their 1941-1942 catalog and sold it under their house brand as the Marvel Minature Camera.
The run was brief. After 1942, both the Model R and Acro Scientific Products Co. vanished from ads and catalogs. World War II shifted manufacturing priorities, and many small camera companies didn't return. Acro's listing in the 1940 Chicago Red Book Yellow Pages under "camera mfg. and wholesale" was gone by 1941. The company is possibly tied to the "Chicago Cluster" of brands linked to Jack Galter of Spartus, and it left no clear paper trail. Its president, Samual E. Schulman, led Commonwealth Utilities Company at the same address, but Acro's fate remains unclear. The company also made Recodiscs, a cardboard Statue of Liberty clock, and a projector.
Collectibility & Value
Original pricing in 1940 was $15.00 for the f/4.5 version and $18.50 for the f/3.5, roughly $318 and $392 in 2023 dollars. Today the camera is described as "VERY RARE," yet one collector reports paying about $20 on eBay.
One common failure is a jammed focus wheel, which turns up often enough that buyers should watch for it. No other widespread failures are documented, and weight and dimensions remain unknown. No detailed repair guides or service manuals have surfaced, so fixing one takes patience and a willingness to improvise.
Despite its obscurity, the Acro Model R has its fans. It’s been called “an exceptional and unique camera that deserves a spot in history and collections alike.” And for good reason: it’s a snapshot of a fleeting moment in American camera design—when a small Chicago company briefly out-innovated the competition with a plastic-bodied rangefinder that shouldn’t have existed, but did.
