From a local estate, it seems to be in working condition, although it likely hasn't been used in many years. It may need a thorough cleaning or gentle 'tune-up', etc.

The buttons / knobs / levers / shutter seems to function as-intended. It needs a new battery, but the meter needle moves, so the electrical components seem to be working. 

The self-timer might have an issue... it's like it 'counts down' but then kinda stops at the end before firing the shutter.
