From out of a long closed  (17 years) Western Ma. Luthiers  / vintage guitar shop . An old Hofner black plastic guitar bridge top without the  adjustable saddles  (Warwick Sells saddles for these )  and another Hofner type guitar bridge top. Probably from a  1960's Japanese import electric guitar . I have included a shot from the Hofner website showing this bridge ,and another of what it would look like with all the parts. THE BRIDGE IS FOR REFERENCE ONLY IT IS NOT INCLUDED.   This store closed over 17 years ago, and was in business for a long time. I am not a vintage guitar or instrument expert . I am going by old tags , masking tape, and penciled notes., The pictures are the description. These are used guitar parts  This will ship via priority mail fully insured for
