WWII chore coat.

As the weather is slowly turning down here in the antipodes my minds wanders to winter looks. Searching through the vaults today I turned up this old favourite. 1940's slubby indigo denim chore coat, blanket lined, 2 pockets, donut buttons and this wonderful early wings and star twill patch sans the red centre spot. Who wore this jacket 70 years ago? An Army Air Corps mechanic perhaps? This jacket would certainly have kept some 'fix'em up' boy warm whilst on hanger duty!
