The Minolta Vest 4×6.5cm bakelite camera released in 1934 was a commercial success and was backed up in late 1935 or early 1936 by the cheaper Baby Minolta. In 1936 the Molta company opened a factory at Amagasaki (尼崎) specifically for the bakelite models (initially as the subsidiary Nihon Kōgaku Kikai Kenkyūjo, later merged into the main company). The more expensive Minolta Six was released some months later, as an evolution of the Minolta Vest in 6×6 format. It is sometimes said that it was the first Japanese 6×6 camera, but it was predated at least by the Mulber Six released in late 1935.

The construction of the Minolta Six is very similar to the Minolta Vest 4×6.5 camera. The body is made of some sort of plastic, perhaps bakelite. The lens and shutter assembly is mounted on a front plate, itself attached to a collapsible structure composed of three rectangular sliding boxes. These boxes are made of the same plastic as the rest of the body, reinforced with metal parts. The result is like a folding camera with no bellows.

The front plate is pulled out by two small handles and there is a table stand attached to the bottom. There is a folding optical finder in the middle of the top plate, with a red hairline cross on the front element. The advance knob is on the left end of the top plate and film advance is controlled by a red window. The back is hinged to the right and a leather handle is attached to the back latch. The bottom plate has film flanges on both ends and a tripod thread in the middle. A nameplate marked Minolta Six, of which two variants are known, is screwed to the front of the body.
The camera shares some parts with the Semi Minolta I, notably the bottom film flanges and the back latch and leather handle are the same as the parts mounted on the early versions of the 4.5×6 folder. The folding optical finder has the same base and back part and only the front part is different, because of the format.

The camera exists in at least three versions:
- f/5.6 lens, Crown C shutter, T, B, 25, 50, 100, 150 speeds;
- f/4.5 lens, Crown B shutter, T, B, 5, 10, 25, 50, 100, 200 speeds;
- f/4.5 lens, Crown S shutter, T, B, 5, 10, 25, 50, 100, 200 speeds, self-timer.
The lens is front-cell focusing and is called Coronar Anastigmat Nippon on all the models. It normally has 80mm focal length, and the aperture is set by an index at the bottom of the shutter plate. This lens was certainly made by Asahi Kōgaku, like the 75mm Coronar lenses of the Semi Minolta and Minolta Vest, and the serial numbers might run in the same sequence.
The shutter is a version of the rim-set Crown in #0 size. It is everset and has a release lever and a distant release connector at the top left — as seen from the front. The shutter plate is marked PATENTS–NIPPON at the top, and has three metal stripes on each side of the lens. The three versions show subtle differences: the Crown C has two additional screws at the top right and at the bottom left; on the Crown C and Crown S, the aperture scale and the CROWN name are directly inscribed at the bottom of the shutter plate, whereas they are on a separate plate attached by two screws on the Crown B.

Commercial life Edit

The Minolta Six was released in late 1936 — Minolta's fifty-year history specifies November. The earliest known advertisement is in the December issue of Asahi Camera. It says that the camera is a new model and shows a sketch of the very first version with angled nameplate (see below), instead of a picture or detailed drawing. The three versions are mentioned (f/5.6, f/4.5, f/4.5 with self-timer) but the speed range is quoted as 25, 50, 100, 150, T, B in all cases, and no price is given. The camera was also featured the next month in the new products column of the same magazine.
Advertisements dated 1937 to 1940 list the same three versions; the prices are ¥40, ¥53 and ¥60 in August 1937, and ¥46, ¥60 and ¥70 in January and July 1938 and in January 1940. The pictures show a metal advance knob and a nameplate with rounded ends, but do not allow to tell the number of red windows or the exact shape of the advance knob. At least one advertisement or leaflet in English language is known; it is not clear if this was published for foreign residents in Japan or for export.
The Minolta Six is mentioned for ¥75 in the list of set prices compiled in October 1940 and published in January 1941. The camera is mentioned in the introduction of the October 1941 catalogue by Asanuma Shōkai, presenting the Minolta range and the lenses and shutters equipping the various models; however it does not appear in the main pages, and it was perhaps not available for sale any more. The official price list dated November 1941 nonetheless has a "Minolta Six" and a "Minolta Six II", listed in the same price category with no further detail.
Three red windows Edit

The original version has three red windows in the back, near the bottom. Each has a reminder, respectively reading 1357, 2468 and 1'3'5'7' from right to left, marked on a metal plate covering most part of the back. This complex advance pattern was needed because the paper backing of 120 film was not yet marked for 6×6cm format at the time the camera was introduced. The entire metal plate slides vertically and acts as a red window cover when in the down position.

The very first examples have an angled nameplate, only observed so far with the f/5.6 lens. This was soon substituted by a newer part with round edges and a different typeface. From that date, all three lens and shutter options are confirmed to exist.
The early cameras also have an all-metal advance knob with a flat top, attached by a small off-centre screw. After some time, this was replaced by another metal knob with a recessed top, normally covered by a leather piece, which is often missing today.
Single red window Edit

The camera's back was modified at some point to have a single red window in the middle, protected by a horizontally sliding cover. This change occurred after the films were sold with 6×6 numbers, probably not later than 1937.

During a transitional period, the cameras were assembled with the older back part, transformed with a single red window. On various examples, such as the one pictured above, the holes for the three original red windows appear under the leatherette covering.

Bakelite knob Edit

The late Minolta Six have a bakelite advance knob. The metal knob is still visible in the January 1940 advertisement cited above, and the change probably occurred at a later date. Examples with a bakelite knob are known to exist with both lens types, but none has yet been observed with a self-timer.
Case and accessories Edit

At least two types of cases are known. They are embossed Minolta Six. The old type has a rectangular transparent window on the rear to show the back plate, whereas the new type has smaller openings for the single red window and its sliding cover.
It is said that about 4–500 examples of the Minolta Six were produced per month in the Amagasaki plant. The lowest reported body number is 3299 and the highest is 19324, in a sequence which was probably specific to the Minolta Six. The known lens numbers run from 18928 to 98111, and the sequence was probably shared with other cameras having the Coronar lens. From the body numbers, the total production can be estimated at about 20,000 units, which is quite consistent with the monthly rate and four-year production run.
