(3) Vintage single gold-plated GROVER Rotomatic guitar tuning machine head.  There is wear of the gold-plated   VIntage model from the 60's or 70's, featuring a "kidney bean" style tuning button.  The housing is stamped with the "Grover" brand name.  They were commonly used on vintage Gibson electric guitars like the Les Paul SG.   I have no need for them.
