Bought by my parents in the late 70s. Reused by me in early 2000's. Still works as far as I know but honestly haven't tried to stick batteries in it the last 5 years.
Lens is in good condition, mechanism inside is clean. Takes 6x AA batteries. I don't know if the telescopic microphone that came with it works or not, never tried.
EE Lock has been broken since pre-2000's so I just used take to keep in place. Handle can fold up against camera body.
Cool just as a vintage decor piece.
