I'm listing this Pentax AF540FGZ II as a heavily used flash with limited testing.
It powers on, the LCD comes up in P-TTL mode at 16 mm, and the ready/test lamp lights. The body has extensive scratches, rub marks and finish wear from regular use. The small front panel below the flash head has visible age/yellowing, and the serial label is too worn to read.
I haven't completed a camera-mounted test, so I can't confirm actual flash output, P-TTL communication, motorized zoom, recycle time, wireless operation or high-speed sync. The battery compartment has not been inspected.
The sale includes the flash unit only. Batteries, stand, pouch, box and manual are not included.
