This is a very well done homemade modification of FED3 into a 6x9 Medium format camera.

Camera is equiped with а 23-У enlarger lens with Ж3С-5 filter. FED 3 body is used only as a shutter.

An enclosure with rail bed system and bellows is attached to the FED3.

The Rangefinder and viewfinder windows on FED are blacked out with what looks like black paper.

A turn knob on the side allows for moving the FED body on the rails and focusing the lens. There is a lock/unlock lever under the turn knob to fix it in place.

On top of a body there is an attached Blik rangefinder that is covered in the same type of black leatherette as the rest of the sheet metal enclosure.

The viewfinder taken from some kind of German camera is mounted on top of the Blik rangefinder.

To the side of the rangefinder there is a locking mechanism with a release button for the Hasselblad-style Linhof Rollex rollfilm adapter camera back that slides out when the button is pressed. The back opens up and the magazine with spool mounts for 120 type film spools is removable. The back also contains the removable cover for the the exposed film just like in Hasselblad (Salyut) cameras, which can mean that there may have been multiple interchangeble backs for this camera.
