Sankyo 8mm sound and film camera (Vanier)

Sankyo Sound XL-320 Supertronic 8mm sound and film camera. Runs on AA batteries. I don't know if you can get film for it anymore or if there's a place that still develops the film. Comes with telescopic condensor microphone, remote on/off switch, carrying case, and manuals. I haven't used it in 40 years so I don't know how well it works; it's just been sitting in its case. Probably not useful unless you're a film camera enthusiast or expert.
