Pearlette
From Camerapedia.org
The Pearlette (パーレット) is a Japanese folding camera taking 4×6.5cm exposures on 127 film, made by Konishiroku (later Konica) between 1925 and the war and advertised again in 1946. The Pearlette is historically significant as the first mass-produced Japanese camera.

General description
The Pearlette is a near-copy of the Piccolette by Contessa-Nettel. Both are inspired by the Vest Pocket Kodak.
The front standard is mounted on a pair of scissor struts and extends to the bottom, acting as a standing leg. There is a round cut-off on each side of the body to pull out the front standard easily. A brilliant finder is mounted at the top right of the front plate.
The front standard is marked Pearlette at the bottom.
Old model: side loading
The old Pearlette model has a removable side plate for film loading. There is an advance key at the top left and a tripod screw at the bottom right, as seen by a photographer holding the camera vertically. This model always has an RK logo at the top left of the front plate.
Wollensak lens and shutter
The original version was released in 1925. It has a N°0 Woco shutter by Wollensak, marked N°0 WOCO above the lens and WOLLENSAK U.S.A. below. The speed is set by an index at the top, with T, 25, 50, 100 or B, 25, 50, 100 positions. The aperture scale is at the bottom. This model exists with a Delta Aplanat 75/6.3 lens and with a meniscus lens whose aperture is perhaps f/8 or f/11. Both are fixed-focus. The original version has no frame finder.[1]
A wireframe finder was added in 1929. The wireframe is hinged to the front standard and supports a close-up lens in the middle: when the wireframe is in the folded position, the close-up lens stands in front of the taking lens. There is a simple eyepiece attached to the camera's back.[2]
In 1931, the wireframe hinge was reinforced and the front plate was enlarged a little.[3]
Pegasus shutter
The imported lenses and shutters were replaced in 1932 by equipment made by Rokuoh-sha. The Pearlette has a Pegasus shutter giving B, 25, 50, 100 speeds. The shutter plate is mottled and marked PEGASUS at the top and ROKUOH-SHA at the bottom. This version exists with a Hexar Ser.II 75/6.3 lens and with an f/8 meniscus lens, said to be made by Asahi Kōgaku.[4]
An additional close-up lens for the brilliant finder is attached to the front wireframe,.[5]
New model: hinged back
The new Pearlette model, released in 1933, has fixed side plates and the back is hinged to the bottom. There is an advance knob at the top right and a tripod screw at the bottom right, as seen by a photographer holding the camera vertically.
This model was first sold with the Pegasus shutter but it was soon replaced by the Echo shutter. The shutter plate is black with a chrome rim. It is marked Echo at the top and Rokuoh-sha at the bottom and the position of the controls is the same.[6] This version with Echo shutter exists with an Optor 75/6.3 lens or an f/8 meniscus lens, both said to be made by Asahi Kōgaku.
The shutter plate was changed in 1937, with a metal stripe on each side.[7] The markings on the front plate were changed in 1940, with the disappearance of the logo and the adoption of a Pearlette name plate screwed to the bottom of the front standard.[8]
