No brand. It says 11AR, so I think it's about M to L size. There is a small hole in the left pocket. There are discolored areas on the button strings. Also, it may be difficult to see in the photos, but the synthetic leather where the strings are sewn on may be peeling or discolored due to aging. Measurements when laid flat: Total length: 99cm Shoulder width: 41cm Sleeve length: 58cm Body width: 54cm
