Like duhhhh, why can't I figure this out? I know its not rocket science, the little brass plate on the camers should say it all, right? Can any of you experts talk me through this? Thanks!

It's exactly the same as the Anny, with this exception: instead of letters ( A - B - C- D ), you have curtain apperture (slit) widths. These show in the little window by the winding key, just as the letters do on the Anny. Tension numbers are the same. No other differences.
Have fun with it ------
