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.

Mission objective was to deploy the TDRS-B communication satellite, cancelled due to IUS failure. Most of the crew would be reassigned to STS-51-D which flew in April 1985 (except for Patrick Baudry, who was re-assigned to STS-51-G which flew in June 1985).

The A-B Emblem patch has a cut edge around the body and a sew-on tab. There are two colors of twill background, dark and light bluie. There are also two colors of sew on tabs, a dark blue and light blue as seen in the photos:

• Type 1, Dark blue main body with dark blue tab. (Hard to find).
• Type 2, Dark blue main body with a light blue tab. (Very Rare). 
• Type 2A, Light blue main body with a dark blue tab. (Extremely Rare).
• Type 3, Light blue main body with a light blue tab. (Hard to find), but the most common of the 4 patches. 

The photo on this page are the "Type 1" issue.

The Swissartex patch has a merrowed edge all the way around the body and a sew-on tab.

STS-41F, scheduled for launch on Discovery, had a crew of five whose names were arranged around the body of the patch. The STS-41F mission was cancelled not long before the scheduled launch and a series of crew reassignments and orbiter and payload changes followed. Eventually the original crew found themselves scheduled to fly again on Discovery with two additional mission specialists added, making it possible to reuse the original STS-41F insignia with just an additional name tab at the bottom. This allowed AB Emblems and Swissartex, who had apparently already begun manufacturing patches for the STS-41F mission, to re-use these patch bodies for the STS-51D mission with sew on name tabs at the bottom.
