Functionality: the lens is working - the lens elements are clean, the focusing and aperture expansion operation is smooth and easy. The viewfinder is clear and viewfinder visibility is good - no distortion or aberration. The diaphragm blades are dry and free of excess lubrication. The corrugation is intact without holes. The shutter is functional: shutter speeds “1/100” and “1/50” work perfectly, but at shutter speeds “B” and “1/25” seconds the blinds do not close completely when released, the light aperture remains partially open (needs lubrication and light service ). Your package will be very securely packaged and shipped from anywhere in the world, depending on where I am at the time.
