STS-6 was a NASA Space Shuttle mission conducted using Space Shuttle Challenger, carrying the first Tracking and Data Relay Satellite, TDRS-1, into orbit. Launched on 4 April 1983, STS-6 was the sixth shuttle mission and the first of the ten missions flown by Challenger. The mission took off from Kennedy Space Center's launch pad 39A, and landed at Edwards Air Force Base on 9 April. This was the first Space Shuttle mission during which a spacewalk was conducted, and the first in which the Extravehicular Mobility Unit (EMU) was used.

This version differs slightly from the regular Lion Brothers STS-6 patch and is much more scarce. 

The wider, taller typeface for the names gives this patch away.

Skylab 1 (also SL-2 and SLM-1) was the first manned mission to Skylab, the first U.S. orbital space station. The mission was launched on a Saturn IB rocket and carried a three-person crew to the station. The name Skylab 2 also refers to the vehicle used for that mission. The Skylab 2 mission established a record for human spaceflight duration. 

Is is possible that the Wolf-Brown patches are repackacked A-B Emblem patches.

The A-B Emblem version is available with both cloth and plastic-coated backs.

The names of the astronauts are larger than the A-B Emblem version and the IUS is stitched narrower.

This patch bears the crew initials between the solar arrays above "Weitz"

This is a Lions Brothers' hallmarked patch for Skylab I. The initials of the crew can be found hidden on the right side.
