I'm guessing this is the officer who started as a KC-135 pilot and volunteered for F-4s.
Therefore, it depends when your uncle was on active duty and the command he was assigned.
Flight suit rank insignia could be on black leather, full color on sage green or blue, or sealed in plastic.
So, KC-135 crews were assigned to the Strategic Air Command (SAC) and more than likely wore leather rank insignia or full-color embroidered on sage green.
F-4 crews were Tactical Air Command (TAC) and those crews might wear the same insignia unless in Vietnam. Those crews sometimes wore subdued insignia
on OD green.
Pilot trainees were assigned to the Air Training Command. That command often wore full color insignia embroidered on blue.
He would have worn a leather name tag or sometimes a white embroidered name tape with wings embroidered on sage green.
However, for your display, I'd suggest just getting a metal set of major's leaves.
