Does anyone have information on Bell & Howell 675/XL Director Series Autoload camcorders?

this is a motion picture camera, not a video camcorder. "auto load" probably means it uses Super8 mm film. Super8 came out in the mid 1970s and became obsolete i n the mid 1980 when video camcorders came out. you can buy film, but you first need to find a lab that can process, as Kodak no longer processes 8mm movie film. The film itself is not cheap, Kodak color film will cost you over $200 an hour, and it is silent. It is also "faster" asa than 1970s film so you may need to get ND filters to compensate.

The hole in the bottom is how it mounts to a tripod. most Super8 cameras were battery operated, not spring wound. You can tell if there is a place for batteries. a "hand crank" camera would be from 1910 or 20s, long before either 8mm or Super8 film was used.

Yep, that manual is not cheap. It uses 8mm film cartridges and those can be found on the net (see link). I would take it to a camera/video repair shop. They can tell you more about it.

I am sorry but I don't know about this

Not really sure
