Vintage Lm Yashica-mat Copal Mxv Camera 80mm Twin Lens W Leather Case

I ran the camera through a full mechanical test without film. The crank advance mechanism winds and resets properly, and the focus knob moves smoothly. I tested the shutter at both 1 second and 1/500th of a second, and it fires accurately without sticking. The aperture blades are also completely clean, oil-free, and open/close smoothly. The selenium light meter is alive and responsive. The needle moves actively when exposed to bright light, though I cannot guarantee 100% calibration accuracy due to its age.
