Article - Vintage Yamaha FG tuners

This is an ambitious project, due to incomplete data I've discovered.  Someone sent me a link a to a Yamaha Parts List Page that includes; tuners, saddle, nuts, bridge pins, nuts, truss rod cover, and screws.  I've been manually copying the data to my Yamaha Archive spreadsheet.  Unfortunately, the data is mostly only for Japan models from the early 70's and up, very little data for the early FG's.  And there are still some major models missing.  But by looking at pictures of tuners of models in this list hopefully I will be able to figure tuners used on exported models.

Currently extracting data and writing article.  Still need to find pictures of tuners and compare to pictures of various guitars.
