I am trying to help a friend to identify two cameras. They both have bellows, and this is the information that I found printed on them: 1. Orionwerk AKT.GES. Hannoer 2. Vorderlinse D.R.G.M. there were two lenses that may or may not go to these cameras, the info was: 1. IBSOR D.R.P. 13.5 cm No. 159560 Steinheil Munchen Doppelanastigmat unofocal 1.6.8F 2. Vario Doppel Ahastlgmat 1.6.3 F-13.5cm Laack Rathenow 133859 On the lenses, I have found that Steinheil, and Laack are the makers. On the cameras, any information would be greatly appreciated.. or even where to look! Thanks!
