Vintage Marshall Field single breasted single vent overcoat size 42 black

Measures about 23” pit to pit and 42” shoulder to waist. There is no fabric marking inside that I see. It is thick and I am thinking wool but might be something like camel or cashmere. There is a little bit of pattern in the fabric when looking closely. Wear or moth damage on edge of left pocket. Single breasted. Single vent on the rear.thick and soft. Lining is in good shape. Lining is plaid on the lower half.
