Comptoir Photographique du Pont de Fer - Detective (c.1900)

Home
Detectives
This camera is a Detective. The only evidence I have regarding its origin is the label fixed on it front by the initial vendor : "Comptoir Photographique du Pont de Fer - 14, Boulevard Poissonnière - PARIS". The body (height: 19cm, width: 11cm - depth: 23cm) is in wood covered with ochre leather. It has two viewfinders allowing horizontal and vertical framing.

On the front, below the shutter, there are three identical buttons :

 
bullet

On the right is a knob for cocking the shutter,

bullet

In the middle is the focussing knob (graduated form 3 to 30 meters),

bullet

 The last knob on the left, is used to select one of the two apertures.

 

There are two shutter releases on the right of the camera : The one above maintains open the shutter as long as it is depressed. The other one below is the regular shutter release but its speed is unknown.

The shutter is of the guillotine type.

This camera can hold 12 plates of the format 9 x 12 cm (each plate is fixed on a metal sheet labelled from 1 to 12). After each shoot, it was possible to reload a new plate without opening the camera. Using the lever on the upper right of the camera moved the shooted plate in the bottom of the black chamber.

On the back of the camera, there is a small counter which was used to count the remaining plates.
