STS-51E - "Baudry" - 4" - Swissartex

This is the first version of the Swissartex STS-51E patch, made when CNES astronaut Patrick Baudry was added as a payload specialist. The body was already designed so he was added as a tab. A later crew change added Ed Garn which necessitated another patch change. Rather than destroying the patches produced up to that time, it was decided that the main body could be preserved and the Baudry tab could simple be cut off and the new Baudry/Garn tab could be glued on to the body. 

To date (2015) only 4 patches are known to have survived the removal of the tab and are in private collections.
