This is a vintage Sho Bud pedal steel tuning key head.  It is in very good shape.  All of the tuners work well and the string rollers move well too.  There is some patina and pitting in the metal but nothing serious (see pics).

String to string (outer 2) measures 68.4mm.  

Top of roller to the bottom face is 33.6mm.

The whole item length is 168mm.

Thanks!
