I was gifted an compact Voigtländer sheet film camera. I haven't worked hands-on with large format before, so it took me a while just to figure out how to get the front open. Would appreciate any information about its qualities and manufacturing origin (Voigtländer has to be one of the most vague names in the business). It has so few identifying marks that I can hardly begin to google it. I believe from measuring the opening to the film holder that it's quarter plate (3.25x4.24"?). Attached are three photos. One overall, one closeup of the lens and one of the little plate that has what seems to be manufacturing info on it.
