Frits, You will have to check Boz's site. I have catalogues with the Ref Converter II listed, but have never personally seen one. I believe it has a mirror rather than prisms which is why the objects in the viewfinder are laterally reversed.
I know for sure that the M and A ref converters fit everything from the ME to the LX to PZ-1p... you say the *ist D too. All of the earlier ref converters from the model II and earlier are said to fit the viewfinder on the K1000 (KM, KX, K2) and spotmatic era cameras. I have never owned one of them, but this is what everyone has said. In the archives from about 5 years ago, somebody talked about custom modifying a magnifier by widening the viewfinder opening with a grinder. I suppose you could do this on the older ref converters too... if I have the sizes right. Regards, Bob S.
