VTG Pendleton Jacket Womens 12 Large Brown 3/4 Sleeve Wool Dress Trench Overcoat

VTG Pendleton Jacket Womens 12 Large Brown 3/4 Sleeve Wool Dress Trench Overcoat I am not sure if the sleeves were altered or if the jacket was meant to be worn as a 3/4 sleeve. The sleeves do not appear altered but may have been professionally done. I am not sure. Small area where fabric is thin on the side under the arm (see photo 4). Overall clean pre-owned condition, shows signs of gentle use. Please see photos for measurements.
