STS-41G
The STS-41G crew wore the standard AB Emblem embroidered mission emblems on their flight suits and on their in-flight clothing, thus there is no rare 'crew patch' for this mission.
It is noteworthy that the STS-41G mission saw the introduction of the first add-on name tab, something that became a feature of many Shuttle missions that followed. This was required because additional crew members (in this case two payload specialists) were assigned to the mission after the mission insignia had been designed.
Because the core part of the insignia remained unchanged patch manufacturers who had already begun to produce mission patches at this point were able to re-use the patch bodies by producing separate tabs that could be glued and sewn to the bottom of the bodies. Manufacturers who had not yet begun their production runs before the crew change, as was apparently the case for Lion Brothers, were able to take a different approach and manufacture single piece patches with the name tab incorporated.
Embroidered Mission Patches
A-B Emblem patch
The AB Emblem patch was the version used by the crew. These were produced as a round body with a separate name tab sewn-on at the bottom.
Lion Brothers patch
The Lion Brothers STS-41G mission patch only exists with a vacuum-sealed plastic backing and was only ever produced as
a one-piece patch with the name tab incorporated into the design.
This is the only version of the patch where the names are executed in upper case, and is also
noteworthy for the fact that the background colour behind the names in the tab area is different to that used
behind the names in the main body.
Swissartex patch
The vintage version of the Swissartex STS-41G mission patch exists both with a waxy plastic backing and with a vacuum sealed
clear plastic coating on the reverse. The fronts of the two versions are virtually identical.
The patch was produced as a round body with a separate name tab sewn at the bottom. Note that in the example scanned here
the tab has the earlier waxy plastic backing but is attached to a body with the later vacuum-sealed backing.
Cape Kennedy Medals patch
The Cape Kennedy Medals patch has very crudely stitched artwork. The design was produced as a one-piece patch without a seaprate name tab.
