Toyoca B35, Chest 35 and Pigeon 35 V

The Toyoca B35 is a Japanese viewfinder-only 35mm folder, made by Tougodo in 1955–6, and the Chest 35 is a name variant.

Description

The Toyoca B35 is a horizontal folder, unlike most other 35mm folding cameras. The design of the main body is clearly inspired from the Retina IIa, with sharp edges and a similar top cover. From right to left, there is an advance lever containing an exposure counter, the shutter release, a small step, the engraving of the name, an accessory shoe and a rewind knob containing a film reminder. This arrangement is exactly the same as on the Retina IIa and the shape of the parts is similar too. The Toyoca B35 only has a viewfinder, slightly offset to the left.

The back is hinged to the right and the back latch is again the same as on the Retina. The Toyoca has no strap lugs. The folding bed is hinged at the bottom, its shape is otherwise similar to that of the Retina. The bed opening button is on the front of the camera, at the top of the leatherette covering under the rewind knob. The lens standard is almost the same as on the Retina, turned 90°, it notably has the same two small buttons to close the bed. There is a PC synch post at the top front of the lens standard.

The lens is a front-cell focusing Owla 4.5cm f/3.5 on the Toyoca B35, and an S. Hasener 45mm f/3.5 on the Chest 35. The shutter gives B, 1–200 speeds and has a self-timer; it is cocked by the advance lever when the film is wound and the camera also has double exposure prevention. The shutter plate is black with white depth-of-field indications and a light-coloured aperture scale.

Commercial life

The Toyoca B35 was announced in May and June 1955 issues of Japanese magazines, and it was advertised from June 1955 to March 1956. The June 1955 advertisement in Sankei Camera lists the Toyoca B35 for ¥8,500 (case included) with an Owla f/3.5 lens and a synchronized NKS shutter (B, 1–200, self-timer). The November 1955 advertisement in Asahi Camera lists the camera for the same price but curiously gives "IJK" as the shutter name.

The Chest 35 is a name variant distributed by Super Shashin-yōhin, announced in the June 1955 issue of Sankei Camera.

Surviving examples

The only surviving example of the Toyoca B35 observed so far is pictured in Sugiyama. It has an Owla Anastigmat 4.5cm f/3.5 lens and a shutter (B, 1–200, self-timer) reported as an NKS-SL.

The only known example of the Chest 35 has a Chest engraving above the top plate and a minor variation in the shape of the folding bed's catch. It has an NKS shutter and the S. Hasener 45mm f/3.5 lens no.3070.
