I have a commercial (no Royal Cypher) BSA No.1 MkIII that was regulated by Fulton and Son of Bisley and is in excellent condition, very accurate, and sports a PH5A micrometer peep sight. I was the high bidder of a Gunbroker auction for it and held off some spirited bidders. I paid a little more then $2,000usd for it and was delighted to be the winning bidder.
