US Military Officers Jacket Suit Coat by Lan-C-Air.  I believe it to be from WWII  

Men's size 40?  There is handwriting on the inside label that appears to say 40.  Please go off actual measurements to ensure an accurate fit.

Great vintage condition overall - some minor discoloring on the inside liner.  See pics.
