Thank you for viewing. This is a National PE-321SW strobe. It comes with the box, original case, manual, etc. (Images 11-13) It looks almost new, with very little signs of use. Operation has been confirmed, and it works. It has an auxiliary strobe. (Image 8) It can swivel up, down, left, and right, and it has zoom functionality. (Image 10) The LCD screen is in good condition, and the backlight can be turned on and off. The charge lamp also lights up. (Image 9) This strobe can do a variety of things. It can be used with old film cameras and digital cameras (if they have a standard hot shoe). Notes: This is a one-of-a-kind, very old product, so returns and exchanges are not possible. Some repairs may not be possible. If you have any concerns, please feel free to ask questions. I will answer them as best I can. Prices vary, but I would appreciate it if you would take good care of it. Thank you for your interest.
