The #2 OK Paper Fasteners originally used on many mandolin rails
are still available.  The product rights have changed hands a number
of times and they are now part of the Labelon/Noesting family.
They can be purchased retail from :

  Southern Oregon Stationery
  916 South Central Ave.
  Medford, Oregon 97501
  tel.: 1-514-779-3123

Ask for #2 OK metal paper fasteners.  They may be available from other
sources on line, but these folks have boxes in stock.  These are the
same as the old style, but with less imprint definition on the dished
back side, possibly due to worn dies.
