TOS 3rd Season Red Engineering Tunic

Loose threads are present on the arms, where braiding for the rank of Lieutenant was once attached. The Engineering patch is a second season patch, slightly smaller than those of season 3. Last photo show screenshot and closeup photos of a patch from the early 3rd season episode "Spock's Brain" to see an identical version of patch design worn by James Doohan.

Handwritten inscription "42" along the inside seam of the zipper.
