Special Form Certificates
The serial number for each source has a two- or three-digit prefix that is associated with a special form certificate (as shown in the table below). For example, a source with serial number 75-2345 (prefix 75) is associated with special form certificate USA/0614/S-96.
The special form certificates are available in Adobe Acrobat 3.0 format.
Some of the values in the Source Serial Number Prefix column flagged with an asterisk (*) may no longer be considered special form materials. Visit the Special Gauge Shipping page for more information.
