My grandfathers service record listed him as some sort of Navy motion picture something or other. He was a repairman after the war. I've looked at the stacks of manuals (and other stuff) many times and thought about just throwing it all away. But I always think. What a waste. If you have a make and model number I might could take a look. But I ain't promising anything. Its a pretty daunting task. I don't think he was much of an organizer.
Side note: I do know that safety is a major concern. Somethings can bite even after the power is off and unplugged.
