Chinon CM-4s mechanical camera with a 1 to 1000sec shutter speed range plus a B setting for all your creative needs. Has a Pentx K lens mount for low cost system. Solid and reliable shutter and robust body. Cable release socket, self timer, hot shoe. Buy a cheap exposure meter and you have a great starter camera
Penta prism looks like it's been removed and glued back probably trying to fix the meter which isn't working. That said the rest is good, shutter fires at all speeds.
