Purchased to swap out the tuners on my mandolin. Unfortunately the existing bushings were glued in and the risk of damage to the headstock in removing them was too high so I had to order more tuners that matched the original bushings.

These Rubner tuners are precisely made and the smoothest I've used. A considerable improvement over the usual Grover, Gotoh and Schaller parts They are the nicest mandolin tuners under £500 that I've experiences; and that includes Waverly models which can be overly stiff.

The roller spacing is a standard 23 mm. The spacing between screw holes is also 23 mm for the lower four screw holes with the upper hole 26 mm apart. Note: the Rubner website is incorrect, indicating that it is the lowest screw hole with the wider spacing. 

The last two photos are from Rubner and show some other dimensions.
