Gave the camera a once-over today. Pretty decent find from a curb-side dumping.
The camera seems to be intact and functioning normally. A bit dirty, sure, but possible to clean. The interior looks decent with only a little amount of corrosion in the battery compartment and behind the film cover.
Sadly the flash's foot is broken. I'll keep the components and use it for other projects but it will never be used, as is, with a camera again.
The filter is intact and still in its original packaging. This is a happy accessory to find and I will enjoy using a lot for B/W photography.
