Beautiful Nikon collection, see photos for details. - Nikon F-401 - missing metal part in battery door ad little loose battery door, tested with another metal, the camera is fully working - Nikon F-501 - self-timer is almost always on - the shutter curtain does not open properly, shutter release works best with open film door - a strange flaw - Nikon F-601 - fully functional but the film door cannot be locked (only with tape) - small locking pin is broken - Nikon N8008s - the camera powers on and all buttons and functions seem to work properly but when pressing the shutter button, the camera makes an untypical sound like advancing the film but it sounds like there is a malfunctioning gear and the film is not advanced. Tested with the flaws mentioned above.
