No. 4 Eureka (1899)

The No. 4 Eureka is a low quality boxcamera for 4 x 5 inch (10 x 13 cm) pictures on glass plates in double plate holders. It can also be used with a roll holder to take photos on film.
Because the camera takes bigger sized pictures it was not possible to use a fixed focus lens. So it has a key on the side to set the proper distance with. In the back it also has a door to view the ground glass. The door in the side panel provides access to the plate holders.
The door in the front can be opened to change the diaphragm (3 stops on a rotating sector) or set the shutter for time exposures. For normal use the shutter has one speed.
The camera did cost $ 6. It was made in 1899 only and total production is 4,500.
This camera was renamed No. 4 Zenith for the UK market, as the Eureka name was already in use there by another manufacturer.
Please see the description of the No. 2 Eureka for more information.
