I was told at the vintage clothing store where I bought it that this is an early production M51 with a liner, made of cotton twill. The stencil is faded and almost unreadable, so I don't know the exact manufacturing date. Size is M, but it's a large fit, so I think it's larger than L. Please check the photos for damage and stains, including a hole on the back (photo 7), fraying on both sleeves, a missing button on the left cuff, stains, and missing leather on the left drawstring. Front Length: 89cm, Back Length: 102cm, Shoulder Width: 58cm, Sleeve Length: 59cm, Body Width: 71cm #40s #50s #60s #70s #80s #talon #aluminumzip #zip #talon #fishtail #m47 #m48 #m51 #m65 #usarmy #parka #fishtailparka
