Kawai Tremolo tailpiece and strap button 1960s missing arm worn but usable

This was pulled from a Japanese semi-hollow body guitar that lost it's brand badge but likely Kawai although there are other possible makers.  Lots of scratches and pitting so not pristine but not broken and still functional . Missing the arm but spring is present. Original mounting screws and the strap button which this goes over are included.  $6.50 shipping in the US, $24 elsewhere by first class international service. Thanks for looking!
