Sawyers Mark IV
Sawyers are best known for their viewmaster 3D viewing system, where stereo images are arranged on a wheel. To complement this range, they commisioned or rebadged a number of cameras (including the Ace Ajoy renamed the Nomad). Most of these cameras were of course 35mm stereo, and are highly collectable. However their most noteworthy 127 offering was a regular (though rather nice) TLR – the Sawyers Mark IV.

The designation Mark 4 is a bit strange, as there was never a 1, 2 or 3. I can only imagine that the 4 refers to the 4×4 format, and the Mark bit was put in to give a Japanese camera that Mark Twain/Tom Sawyers link to America culture.
The image and manual were submitted by Dave Schneller who inherited his Mark IV (S#274930) from his father. The following is quoted from http://medfmt.8k.com/mf/sawyer_mark_IV.html by Karl Bryan
The Sawyer’s Mark IV twin lens reflex cameras are a rebadged Primo Jr. Type 1. Manufactured by Tokyo Optical Co. and imported by the Beaverton, OR GAF Co. (makers of the Viewmaster). The Sawyer’s Mark IV Type I was in production from 1958-1959. This camera is a 4×4 format utilizing 127 film. Note that the proper lens cap acts as a shutter release lock.
Shutter is a Seikosha MXL, B, and 1-500 speed with M, F, X flash synch. The camera shutter has markings for EVS (Exposure Value System, also known as the Light Value System). The EVS is a cross coupled system between shutter speed and aperture with EVS values from 3-18. The aperture and shutter settings are viewable from the small window above the viewing lens.
The lens is a Topcor 60, f2.8 multicoated, four element, 3 group, tessar design. F stops are from 3.5f to 22f, film wind is by crank with automatic setting of the shutter. Filters are the typical Bay 1 type.
Film setting is by the red window to frame 1, and then it is automatically indexed. When first installing film, wind the crank until the number 1 appears in the red window in the back of the camera, depress the button above the wind crank and slide the button next to is towards the back of the camera. This set the frame counter to 1, then film indexing automatically occurs every time the film crank is wound.
Focus is by knob with an ASA reminder dial in its end. Above the focus knob is a Depth of Field scale. The film chamber is baffled for flare control.
The ground glass has a fresnel lens with center focus spot and cross hair etched lines for aid in composition.

Seagull TLR Overview- Camerapedia

Seagull (海鸥 = hǎi ōu = seagull) is the brand name used from 1964 by several camera factories situated in the Shanghai region, simply named Shanghai Camera Factory No.1, No. 2, No. 3, … etc.. In the literature they are collectively referred as Shanghai Camera Factory. Perhaps they are most widely known for their fascinating Shanghai 58 rangefinder camera, based on the Leica IIIa, which evolved with some modifications borrowed from Canon and FED, and more recently the Seagull DF cameras, a manual focus 35mm SLR range. The first ones were simply copies of Minolta SR models since they were the easiest to copy. Later the cameras were produced with licence from Minolta. Some SR mount lenses of Seagull’s own brand Haiou were made too.
The Seagull-4 series of TLR cameras, introduced in 1964 and distributed worldwide, is a continuation of the earlier Shanghai TLR; itself quite possibly produced using outdated Japanese tools and manufacturing equipment. These cameras are usually found with knob wind, but the Seagull 4A has lever wind. There are also a range of Seagull 35mm rangefinder models, as well as a range of Seagull folding roll film cameras typical of the immediate post war European production.
Several Seagull camera accessories are known, for example the electronic flashgun SG-100 and several accessory angle finders for SLRs.
In 1976 three of the Shanghai camera factories moved together into the new factory Shanghai General Camera Factory in Song Jiang County. The 35mm SLR series Seagull DF-… was continued there. The Seagull CL-A light meter was made in the Shanghai No. 2 Photographic Equipment Factory.
In 1999 600.000 units (cameras and lenses) could be produced per year. In 2001 Seagull planned to produce digital cameras for Kodak[1].
A most thorough research on the Chinese camera production was carried out by resident Douglas St Denny. He travelled across the vast country during the second half of the 1980s interviewing people there and collecting information which otherwise soon would have been lost. His book “Cameras of the People’s Republic of China” is invaluable for anyone studying this topic.
