STS-9 Uknown make, cut edge

STS-9 (also known as STS-41A and Spacelab 1) was a NASA Space Shuttle mission which carried the first Spacelab laboratory module into orbit. Launched on 28 November 1983, it was the sixth mission of the Space Shuttle Columbia, and was Columbia's last flight until STS-61-C in January 1986. It was also the last time the old STS numbering was used until STS-26 (in the aftermath of the Challenger disaster of STS-51-L). Under the new system, STS-9 would have been designated as STS-41-A.

This 4" patch features a cut, rather than merrowed edge.
