I have an Orion Werk 9x12 camera, it's one of many small German camera companies it was founded in 1893 and went bancrupt in 1933. It changed its name a few times,
The Ibsor shutter is the precursor of the Prontor, it's self cocking and an excellent shutter, Steinheil were a well known optical company.
Laack, based in Rathenow, were a German manufacturer of cameras and lenses,, the Vario shutter is the budget 3 speed shuttermade by the same company as the Ibsor, Alfred Gauthier based in Calmbach, there usualy a 3 blade shutter symbol woth AGC on all their shutters.
Both cameras are most likely 9x12 format, as the standard lenses are almost always 135mm or 150mm, the Orion Werks range were fitted with a variety of lenses, mine has a Rodenstock Eurynar f4.5 135mm in an Ibsor shutter which would have been one of the best lenses then available, in comparison the f6.8 Steiheil would have been a budget lens.
The other lens in the Vario shutter would have been the cheapest lens/shutter option, and often the camera's also lacked the front rise & fall.
Hope that helps, welcome to APUG BTW
