Does anyone have a line on old style Couf pearls? The old style are quite large, concave, and have a ring groove on the back that fits a corresponding ring on the touch piece. The touch piece ring is 12.98 mm ID, 15.06 mm OD, and the pearl itself is 18.00 mm OD. I can manufacture a pearl by gluing a spacer to a filed down pearl and fit it but thought I would see if any techs had any available or knew of anyone who might. Thanks in advance for any assistance.
