Willabee and Ward

A version of the A-B Emblem was recently identified as the type as word by the crew after their flight. The patch is identified by having darker thread used for the crater details on the front. While hard to distinguish from the front, it is readily observed on the back side where the two colors of grey are very obvious. This patch was later made in a replica form for the Willabee and Ward patch set, with a plastic back. 

STS-50 (U.S. Microgravity Laboratory 1) was a United States Space Shuttle mission, the 12th mission of the Columbia orbiter. Columbia landed at Kennedy Space Center for the first time ever due to bad weather at Edwards caused by the remnants of Hurricane Darby.
The U.S. Microgravity Laboratory 1 was a spacelab mission, with experiments in material science, fluid physics and biotechnology. It was the first flight of a Space Shuttle with the Extended Duration Orbiter (EDO) hardware, allowing longer flight durations.
Primary payload, U.S. Microgravity Laboratory-1 (USML- 1), made its first flight; featured pressurized Spacelab module. USML-1 first in planned series of flights to advance U.S. microgravity research effort in several disciplines. Experiments conducted were: Crystal Growth Furnace (CGF); Drop Physics Module (DPM); Surface Tension Driven Convection Experiments (STDCE); Zeolite Crystal Growth (ZCG); Protein Crystal Growth (PCG); Glovebox Facility (GBX); Space Acceleration Measurement System (SAMS); Generic Bioprocessing Apparatus (GBA); Astroculture-1 (ASC); Extended Duration Orbiter Medical Project (EDOMP); Solid Surface Combustion Experiment (SSCE).
Secondary experiments were: Investigations into Polymer Membrane Processing (IPMP); Shuttle Amateur Radio Experiment II (SAREX II); and Ultraviolet Plume Instrument (UVPI).

Very similar to the A-B Emblem souvenir version.

This is the Willabee & Ward issue for their space emblem collection. Appears very close in appearance to the A-B Emblem version.

Part of the Willabee & Ward space emblem collection. The patch very closely resemble the A-B Emblem version.

This is the Apollo 12 patch featured in the Willabee and Ward space emblem collection. It closely resembles the "quarantine crew patch", however, the crew patch was not made by A-B Emblem, but Dallas Cap and Emblem. The back anchor threads differs widely from the standard A-B Emblem souvenir version.  

This Apollo 11 patch is a modern reproduction as made for the Willabee & Ward mission emblem set. The lunar surface has a distinctive linear pattern.

This patch for Apollo 10 was issued as part of the Willabee and Ward set. 4".
