Geez guys, I hate to be the one that always disagrees, but I think the eBay sight is an original that has been reblued and perhaps "touched up" a bit. In the Member Gallery there is an excellent series of photos of real Navy sights and several shots of the repro that is currently on the market. I have borrowed a couple of photos from that album and they are shown below with the real sight on top, the eBay sight in the middle and the repro sight at the bottom. It is difficult to say for sure because all three sights are not exactly the same view, but I think the eBay sight looks like an original.
