The patches look authentic to me…albeit with my limited experience.
My brother was with the USAF in Vietnam and collected patches from the era, so I’ve seen a few.

Most of the name and special event or recognition (“100 mission” ect.) or unofficial patches were made locally (or regionally…Hong Kong, Thailand, Japan, etc) in small quantities so often they don’t look as professional as the “official” USAF unit or aircraft-type patches.
Of course, that semi-homemade look also makes things easier to copy.

The nametag is correct on at least one count…the Command Pilot wings would be correct for a Lieutenant Colonel.
I don’t believe it’s an “official” item though. Note the nickname…everybody with the lastname of Gibson is called “Hoot” (after an American screen cowboy ofthe 30s-40s).

All in all, I’d be very concerned about the lack of a tag…any authentic piece would have one.
