René emailed to ask me the following question:
Do you happen to know the difference between the Rondinax 60 type 6450 and the type 8605?
My answer was that I did not know. My relatively modern Rondinax 60 is in a box marked 6450, as is the instruction manual available for downloading. Was the 8605 earlier? Bakelite? My guess at the moment is that is the explanation since the 1939 Agfa Catalogue for Germany shows the order number (Bestellnummer) for the Rondinax 60 as 605 which could have soon become 8605.
All information from boxes, manuals and catalogues welcome.
