terribly sorry, I must plead ignorance of Ricohs, just read up on it, I like the film advance thing. I played with a Leica version of that once and thought it was a great idea (although as with everything Leica, just ridiculus with prices, why I had Nikon stuff....)
Do you still shoot with it? As I said, I havaent shot with a rangefinder for many years, but there is a lovely unobstrusiveness in the approach isnt there? Im surprised they didnt have interchangeable lenses, although perhaps they did, as again I confess ignorance...
Interesting to read they followed the Nikon et al direction of focusing.

cheers
