Likely from the 1947-50s. The fabric is early-type cotton twill. It's sturdy and the color remains. I purchased this item used, washed it, and have kept it stored at home. It's in good condition with no holes or tears, but please judge from the photos. The size is 46, and it can be worn oversized by a man who is 170cm tall and weighs 65kg. Length: 82cm Width: 60cm Shoulder width: 48cm Sleeve length: 61cm
