The outline history of Rondinax and Rondix tanks is known but there is still much to find out. For example, when did the change in materials to produce reels with translucent ends take place, or when plastic replaced the rubberized cloth to pull the film onto the reel? There must be information in Agfa and dealers’ catalogues from around the world. Even the date from instruction manuals (the last digits) would provide clues as to which model was being made at a particular time. So, if you have sources of information please contact me. Similarly, are there any former Agfa employees out there with information?
