I have confirmed the battery (LR44) is installed. The exposure meter is working. I have confirmed that the shutter speed changes in response to brightness and aperture. I have also confirmed that the lamp inside the viewfinder changes. The self-timer function works. The bulb, X, functions work. The shutter curtain and mirror are moving in conjunction. The mirror has some dirt, but when looking through the viewfinder with a lens attached, the dirt is not noticeable. It is clear. The synthetic leather on the back cover has some scuffs. The lens has some mold, but it seems to function without problems. I have not confirmed actual shooting, so please understand that this is a used item before purchasing. Shipping will be via Yu-Packet Plus.
