I've never seen one of these in person, but the devil's paintbrush has some pictures of one minus the sight, just the clamp ring. I think one or more of the members here may have one? I am not at all sure this auction can be taken as any indication of the value of this particular item, there was quite a bidding war between two buyers at the end, so they may have run this up more than it is worth, or not. I haven't seen any of these for sale to know!
Pretty neat and quite rare piece, though. Neat! I just wanted to put this up so that everyone could see the sight, these are not common at all, and very interesting to see. I just couldn't get there.
