R-189 REDUCER RING for larger horizontal carriages, to allow a smaller reproducer (such as the C or H or K) to play the cylinders. The Model C/H/K reproducer will fit inside the reducer. Nice, original, shiny metal body (not pot metal). Similar to what is shown in the photos, only even nicer. Third photo shows a smaller reproducer in the reducer ring, how it is positioned there, and in the background is an example of its use in a horizontal carriage.
