The 43rd Engineers is probably worn more as an "affiliation" rather than his current unit. It's very possible this guy commanded the 43rd Engineer Battalion earlier in his career and left this patch on his uniform out of pride.
Yes that would be my conclusion too. Too bad too that someone ripped the NAME tape off, this goes back to a quote I made once in an old topic on the stores that for whatever reason insist on ripping NAME tapes off fatique items that come in, sometimes the U.S. ARMY tapes too, with them throwing the NAME tape in the garbage, but throwing the U.S. ARMY tape in the cheap priced patch bucket, ammo box and or bin. True too, that it could be the original wearer of these items removed the tapes himself for whatever reason, but those reasons will be different then a store's reasons I'm thinking.
