Voigtlander-Braunschweig folding camera w/Anastigmat Viogtar lens 1:7,7

I am hoping to find out more about this camera. From what I can find it is from Germany. I could not find any serial or model numbers.

It is a folding camera with a range finder which makes me think it is pre-1937. The lens seems to be a rare one in that I cannot find anything related to a camera with this lens.

If anyone can provide any information about this and an approximate value I would greatly appreciate it.

Thanks.
