These are tuning pegs that were recommended and installed on my instrument by the contrabass workshop "Gengakki no Yamamoto." While there is no remaining information about the name in print, I believe they are made by Rubner due to the reliable recommendation from the workshop, their unique shape and craftsmanship, and their smooth and precise operation. Please check the photos and make your own judgment. ・Used, one-owner item. ・Set of 4. ・The lengths of the shafts for winding the strings are approximately 57mm / approximately 54mm / approximately 49mm / approximately 47mm (※). ・There are minor scratches and dirt from use. ・Mounting screws are also included (see photo 3/3). ・All items are shown in the photos (the instrument they were attached to is not included). ・Sold as is. (※) These are approximate visual measurements taken with a ruler from the base of the shaft to the rounded tip. Thank you.
