How many of these pre-War Aeros in any size does one see? Looking at the jacket the proportions might not suggest a size 50, so I've asked the seller for the dimensions. This was Aero's second contract for the USAAC, order number 38-1711-P. There are pics of one on JC's CD and another in Full Gear P. 24
