Howdy- I just purchased a Sharps 1874 by Taylors. The rear sight is junk and I'd like to replace it with a buckhorn style sight. The dovetail is larger than the standard 3/8" dovetails and I was wondering if someone knows of a drift in sight that can act as a replacement? I don't want to put a tang sight on yet so I was hoping that someone knows of a buckhorn sight that will fit the dovetail on the Taylor Sharps.
