Hello from the UK. I have a Colt 2nd Generation 1851 Navy Nickel plated and scroll engraved. The engraving was done by B ob Hendricks and the initials BH are engraved on the triggerguard. I have tried to find information on Bob Hendricks but can only find reference to Frank Hendricks. Does anyone have information on Bob Hendricks and was he related to Frank Hendricks?
