Thanks gunman,the little info I can get is they were in production for short time 1978-1982 they made the browning BSS sidelock which was expensive this is that gun with miroku own name. They were hand made and engraved back then miroku put all there emphasis on the metal work hense the 'toilet'seat wood which is a pity. The barrell are well struck up and chromed it's lovely handling and fabulous trigger pulls. I'll redo the wood and checkering might bring out the grain and change the badly fitted but pad
