The trading history of mckay3d was 0, and I just bumped it to 1. I want to publicly say that the purchase from him was flawless. He shipped quickly, packed the lens well, it was exactly as pictured, and even included the original box which wasn't mentioned. What he called "EX+", most eBay sellers would call "Mint". mckay3d is welcome around here!
I'm using this 63mm lens to avoid switching lenses when making small 4x5-inch enlargements from 35mm negatives. With a 50mm lens, my Beseler 45 MCX can't go low enough, so I'd need to put the easel on a box.
