Polaroid 636 Close Up

This is a Polaroid 636 Closeup.
It was released around 1992.
Focal length: 116mm, Maximum aperture: f/11
Shutter speed: 1/200 to 1/4 second
For close-up shots, a plastic close-up lens is set using a slide switch.

It uses high-sensitivity Polaroid 600 film, which is still available today.

I actually used it about a year ago with black and white film.
There is some dust inside the viewfinder, but it does not seem to significantly affect the photographic optical path.
I have not had the opportunity to test it, so I cannot confirm if the flash fires correctly.

There is no instruction manual.
There seem to be user blogs and other resources available online, so please refer to them.
