My first FE (many years ago) (many, many years) quit working on me, and I took it back to the place I bought it. They did a quick repair on it, and it failed again a couple of days later. They wouldn't give me my money back, so I took it to a reputable repair shop in town, and they informed me the shutter was broken, and there were no replacement parts. So maybe it was of the original production run, and Nikon quit making parts for that series since they had changed the design by then. Anyway, it just became a mantle display until it was sold with the rest of my gear when I was raising cash to keep paying the rent.
I got a second one about ten years ago, and never had an issue with it. It seemed to be a very late production version. I believe I have an FE2 also, but don't quote me on that.
