Got this at an antiques dealer in Fort Worth Tx by the air force base. I don’t know the history of the jacket and have only recently learned some of the history of this particular fighter sqadron which was first in the pacific in WW2 and has many interesting and famous exploits that are too many too list here but are easily accessible with a simple google search. Thank you for shopping. Here are the dimensions of the jacket. 27 garment length from base of collar to bottom of jacket. 35 from center of collar to end of cuff. 21 armpit to armpit. Tag says its a medium.
