・This is a socket that was attached to a Japanese-made (Cremona) contrabass. ・Please see photos 4 and 5 for dimensions. 　　　※The numbers are approximate visual estimates using a ruler. ・There are scratches, dirt, rust, and cracks in the wooden (bare wood) parts (see page 3), but there were no functional problems during use. ・It has been repainted black. ・It will be delivered as is. Thank you.
