Recently purchased from swininc, low serial 004716. I resigned myself to the fact that I was not going to be able to justify the current prices of a nice boxed example so I bought what I hoped would be a nice example. It is, with nice gaskets/ rubbers, no stress cracks and one tiny mark at 12:00 on the non-etched lens. Interestingly enough after I did BIN swininc listed another pair. Where do these keep coming from in this condition?
