Cosina was the company licensed to make the Nikon FM10 and produced rangefinders under the Voigtländer name. All of those products were discontinued last year, sadly.
As far as I know, the F6 is the last one still in production.
That’s not unexpected, but still a bit sad.
Incidentally, Cosina also made the rangefinder I’d dub the Leica M7.5 - the Zeiss Ikon-branded ZM. Wonderful camera.
As far as rangefinders go, the ZM IMHO is the one to beat, in close competition with the Contax G2. (Autofocus! In a rangefinder!)
The ‘because we can’ high-end F6 and the entry-level, manual just about everything FM10. (Though I think the current FM10 may be made by others under licence.)
I think Voigtländer may still make a 35mm rangefinder, too.
