If all matching LRHs in very good condition are usually in the $3000-4000 range. It is hard to be accurate with pictures provided and the current market but this is a good "ballpark" auction estimate. Value goes south quickly if the serial number of even 1 part does not match. I can't tell from the images but how is the rear sight marked 1, 2, 3... or 100, 200, 300...?
LRH are usually in the 10,000 - 40,000 serial number range.
