Chronology of cameras Welta 

The Welta Dubla was introduced in 1922 and was produced until 1934. These cameras were designed for 9 x 12 cm and 10 x 15 cm plates, had triple extension bellows, and a two-shutter design (Zweiverschluss).

This particular camera belongs to the batch produced from 1927 to 1931, identified by the horizontal folding type, the brilliant finder on the right side, folding wire frame finder and Z-shaped struts. It also has the long speed table on the shutter side of the camera. The camera is made of wood and covered with black painted leather, and the plate size is 10 x 15 cm. It has a brilliant finder with bubble level and a wire frame finder for rapid setting.

The focal plane shutter has controls for slit width and spring tension (both with numerical scales), delivering speeds from 1/10 to 1/1000 seconds plus Z. The central shutter is a compound F. Deckel Compur with speeds from 1 to 1/200 seconds and Z and D.

The lens is a Schneider-Kreuznach Xenar of 16.5 cm of focal length and 4.5 of maximum aperture.

The front plate has geared horizontal and vertical movements for perspective correction. It is a fairly large camera with more than 2 kg of weight.
