If you pop across to the SLR thread, you will see that Bob has got a good investigation going into Cosina "Badge" Engineering.
My research project could be posted under either thread really, as there were almost equal numbers of rangefinders and SLRs with this bayonet mount.
Background:
The Retina llc/llC & lllc/lllC , original Retina Reflex and the various Continamatic lll, Contaflex Prima/Alpha/Beta (Pantar) Contaflex Super/Rapid/lll/lV (Pro Tessars) of the period left the rear element in place when the lens was swapped. This was not desirable from the point of view of optical performance and anybody who has struggled with the scale focusing on a Retina lllC will appreciate the user's problems.
In the late 1950s the makers of the Syncro Compur shutter evolved a standard bayonet mount that enabled the shutter to be mounted behind the lens rather than in-between the lens elements.
So in comes the new Deckle Compur mount and though Kodak and Voigtlander were the most famous users, so too did Balda, Braun, Iloca, Edixa and possibly others
From memory:
Kodak Reflex S, lll & IV - lllS - Instamatic Reflex
Voigtlander - Bessamatic - Ultramatic
Iloca Electric
Edixa Electronica
Balda Baldamatic lll
Braun Colora (not correct, but a similar sounding name) rangefinder - see post below by David Silver - its the Colorette.
Braun Reflex Automatic (my what a collection of different mounts Braun had - 3 going at the same time in 1961 - One Thread & two bayonets!)
and others?
This "commonality" ensured that lenses such as the famous Voigtlander Zoomar were also available to to fit the Kodak Reflexes with only a minor adjustment
At this time Werra, Agfa, Lordomat & Arette retained their own mounts, but the Regula lllD and the Paxette Automatic were so similar that I tried a Regula lens on a Paxette a couple of years ago. It went on easily, no problem, but could I get it off? That's why I still have a Paxette Automatic in small pieces!
Any additions to the above list or knowledge about the mount would be greatly appreciated
