76 Express sight

[hawkeye2]

        I need a rear sight for my repro 76 .50-95 and was thinking a 3 blade express would be nice but couldn't find one within my budget then I saw mention of one of these in a post somewhere.  It is susposed to be a copy of a 5 blade Winchester express sight.  Has anyone had any experience with one of these or even seen one? I would be using it with a Lyman globe front sight.
