Here's a pair of Vivitar 283 flashes, one I bought new in the mid-70's and one I bought new in the early 2000's when I ended up somewhere without my flash and needed one NOW. Included is the SB-4 power supply to run them from AC, and a 283-to-PC sync cord. Oddly enough, the newer one had a little piece of trim fall off the side shortly after I bought it. I guess they don't make them like they used to! I'm asking $20 for everything, plus $10 shipping in the US (I'll ship anywhere, but we'll have to figure out shipping costs for destinations outside the US.) They work perfectly. One of the battery holders has light corrosion on it.
