Jorg, one of the most impressive Star Trek prop and costume minds out there (with a near photographic memory of all Star Trek episodes), and one of the brains behind Memory Alpha, has put together notes and corrections on this week's auctions:
STAR TREK: ENTERPRISE “ENSIGN MAYWEATHER" UNIFORM
This uniform is not from "Strange new worlds" but from the season 2 episode "Dead stop" when he is apparently killed by the repair station. The uniform is worn by the dead Mayweather clone.

features the Talarian logo and Talarian writing on the back, see here at MA.
STAR TREK: DS9 “FERENGI DISRUPTOR RIFLE”
Originally created as new Romulan disruptor rifles for "Improbable cause" (explaining the Romulan writing on the weapon). Later, the weapon was used as a Ferengi rifle in "The Magnificent Ferengi" and then used my mirror-universe Brunt in "The emperor's new cloak".
