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.
The door in the front can be opened to change the apertures (3 stops on a rotating sector) or set the shutter for time exposures. For normal use the shutter has one single speed.
When the camera was used with glass plates you could focus and frame the picture on a ground glass in the back. To view the ground glass you had to open the door in the back.
The door in the side panel provides access to the plate holders and roll holder.
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.
