These are high quality sidelocks made for Browning by B.C. Miroku in Japan in the 1980s. I seem to remember that only about 500 were made. My wife owned a 20 ga which we bought for $1500 new back then and sold for $5800 2 years ago. Very nice guns. Of course the one at Cabela's is priced too high by at least $1000, but what else is new?
