Prices are very much regional. With all due respect to Seaspriter, a nice '50 Long Branch here in Toronto (the home of CanadianArsenals Ltd.) will run you a minimum of $800 (CDN) and probably closer to a grand, if you can find one. A matching numbers PH5C target sight runs $250. to $300 in very good condition. A nice Long Branch No.4, walnut stocked, matched numbers, and factory original will run $750.+. Restored ones, even with original LB marked parts run $550. to $650. Of course, there are a lot of variables that affect the pricing, but the numbers I'm citing are current to what I'm seeing at present. If the one you saw isn't numbers matching, then it's overpriced, even with the PH sight.
