Comes with original instruction manual, plus the wide angle flash adapter, SW-2. I purchased both in 1979. I just popped in fresh AA batteries, after cleaning all the contacts, and what do you know, the charge light actually comes on. Stuck it on a current Nikon digital camera, fired off a shot and it actually works perfectly. You have to manually pick one of two possible apertures on the camera, using the exposure calculator on top of the unit, based on the ISO (ASA) you are using- state of the art for late 1970's! At some point, I may have dropped it, as there seems to be a piece of tape holding one side of the unit firmly together, but as it's working, I didn't want to mess with it and remove the tape. If you have any questions, just ask me. Local pick up only. Cash only please.
