This is an Asahi Pentax SP. I've checked to see if the shutter fires, if bulb shooting works, if the speeds change, if the mirror is clean, if the timer works, and if the back opens. To ensure it works perfectly, before you press the shutter, please confirm that the inside of the hole is perfectly red, as shown in the last photo. Film is expensive these days, so it's a shame to waste it. I couldn't check the light meter because there are no batteries. There are few scratches, but please check the photos I've uploaded.
