[CAUT] reverse grip tuning pins

[Alan McCoy]

Thanks for all the responses. Yep, Pianotek is the only place I know to get
them. They had the 2/0 / 3 1/2 (.282/.288) when I ordered them last month.

A raid would be fun. Although more fun next spring when the addition is
finished. As it is now I've commandeered my half of the garage for the
summer rebuilding project, where the piano now resides instead of my truck.
