Small Solo Seat in Glazed Black Leather 
$299  and up
This is a great new thin smooth leather with a firm feel, slightly distressed will work in great.
The first three pics are the leather, the rest are examples of the stitching style and design options. Pics will be updated as seats are made.
The Small Solo seat is a 12.5" x 8" nickel plated 16g metal pan very similar to a Bates or Selle pan from the 60's/70's. Spring studs welded on 6" on center.
