Re: 1851 Sherif's Model? BP Revolver
This is actually a .44cal. Griswold & Gunnison type revolver. The marking on the left side of the frame is the Replica Arms logo used during the transition from Replica Arms to Navy Arms when Navy Arms purchased Replica Arms. Check for any other logo that may have an "F" in a triangle. More than likely this revolvers was made by Pietta. Dixie Gun Works and VTI are sources for parts.
