I have the VT De Luxe with inbuilt winder grip, and a unique feature every Leica, Zeiss Ikon and Bessa is lacking - parallax correction for the appropriate external finders.
A very lovely and btw affordable camera, switchable 50mm and 35mm viewfinder (smaller and not as clear and sharp as a Leica M, but better than most compact RF's I know), plus a "RF" called finder position which is intended for better (higher magnified) focusing, which can roughly be used as 135mm finder, too.
To Rover: bigger and heavier than a M3? I can't believe that though I have not a M3 here to compare.
