Wirgin Edixa, a rangefinder camera with a double viewfinder

I found this Wirgin Edixa at a thrift store. The camera has a 45mm/f2.8 lens with shutter speeds from 1/25 to 1/200 plus B. There is a characteristic lens plate on the front that makes the camera's design unique and helps to the strength of the lens controls.

There are two viewfinders in the camera. One is for composing the picture. The other one is smaller for focussing, two separate windows must match the image horizontay, by turning the focus ring.
I cleaned the camera and adjusted the rangefinder, but the advance lever has not enough friction to advance the film. I must fix it later.
