Jacob’s staff adapters are available in a static, non-pivoting form and a gear-drive, fully functional form, as the original would have been.
 
Adding a staff adapter to your instrument makes so much more of a visual impact and makes your rare instrument so much easier to display.
 
Colonial Instruments will match the patina of your instrument to the newly fabricated staff adapter, as well as matching the taper of the ball socket to the taper of the socket of your existing instrument.
