In 25 years of selling camera equipment on eBay I have never seen a flash in such spectacular condition I do believe that this is brand new and completely unused. If it has ever been put on a camera then it was for 10 seconds and taken off. There's no where in the pins the battery compartment is perfection. Let me say that again there is zero corrosion in the battery compartment and nobody left a set of double a batteries in it for 30 years like they did in every other single flash I have ever seen. I almost don't want to sell it because it's just so perfect maybe I should frame it or make it like modern art I don't know. But for you I'll let it go so it's tested and it works perfectly and it's beautiful and perfect in every way yeah I don't even know what else to say.
