If you are reading this ad, then it is still available, so no need to ask. Produced in the early 1960s, this is Pentax's first electronic flash unit, later replaced by the Super-Lite II. Uses a shoe mount to attach to camera, but is not hot shoe compatible. It uses the attached synch cord to fire the flash. It takes 4- AA batteries. $25.
