A rare beast indeed is the 127 rangefinder. In fact I forgot to include a catagory for them until an Acro Rangefinder happened to come into the collection. Rangefinders were also added to latter models of the Foth Derby. The Multex II however has the distinction of being the most technically advanced, as it's rangefinder is coupled. Perhaps rarest of all, in 1937 Olypus protyped their "standard". Only 10 were made!
