Asahi Pentax K1000 SE (Brown Covering)

Asahi Pentax K-1000 SE in brown covering serial number 6051967 meter is working, however, when looking through the viewfinder I see some debris suspended on top. It could be debris on the focusing screen I really can’t tell where it is. The debris looks like camera seal material tiny bits of it are also on the focusing screen? I installed a battery and the meter responded as I moved shutter speed and aperture. Camera has a small dent on, the top, side of camera right behind the "X" on Pentax, (rewind side) I see no other dents. The cameras bottom plate has 7 small numbers etched into it. Battery chamber is clean. I would recommend a thorough CLA`D the camera is not mint but still looks and seems to work very good.
