Just awaiting delivery of a Makina bought at auction, but from the image having trouble positively identifying it. The Square rangefinder windows suggest IIS, however the front lens panel seems to suggest the between the lens shutter of the pre-S models. Also don't think I've seen many (any?) with the sync on the lower left, which is a point of confusion for me. Any help or guidance is welcomed. Also, if anyone can point me in the direction of a service manual for the camera that would be great.
