This is a FED 2 Preseries-Crossover or as some people call it Preseries-2.. It is a hybrid between Preseries and a production model. It still possesed a little lever around the shutter release button instead of a "mushroom" like on production model, but the riveted square front rangefinder window had been replaced by a regular round one.
