Alot of these Government Ribbons I don't have and do not think they can be had as a stand alone ribbon.

What I was told is that when some of the Ribbons/Medals are/were manufactured, the contracting Agency controlled the Ribbon
and gave enough of it to the Medal maker for the amount of Medal sets being made and any left over ribbon had to be returned.

An example of this was the Border Patrol Ribbons,  designed by the U S Border Patrol in 1999. Most of these were never produced in production quantities and an exceptionally limited number were ever awarded to members of the U S Border Patrol. After Sept 11, the Border Patrol was placed under the Department of Homeland Security and issuance of all of these medals was stopped. A proposal made for new designs using DHS logo was never approved and the entire program has been stopped, there have been some sets sold from left over stock which was obtained from the maker.

So for Ribbon Collectors the only way to get some of these Ribbons was to:
A-Buy the set, take out the Ribbon bar and keep or re-sell the rest
B-Buy the Medal and take off the Drape to make up ribbon Bars.
