Pentax AP Film Camera Body Not Working

Serial Number: 146469

It shows signs of use. The case is included but is in poor condition (damaged).

There may be a crack or other imperfection on the top/left of the viewfinder.

The shutter fires but the curtain is slow to fully close so the process of getting ready for the next shot (dropping the mirror, allowing film to advance) gets delayed. Film counter works. No further testing has been done.
