Vintage RARE Hudson’s bay Company Blanket Coat Made in Canada!

Amazing vintage condition. A couple small flaws.. one maybe burn on arm ( not a hole ), some marks inside lining. Not sure if the red cuffs inside are original to the coat or added.. stitching coming undone, could be removed or repaired. Loose buttons and missing hood. Overall this jacket is in crazy good condition. Not finding much online about it but would love any info such as age that you may know! Tag on liner is marked size 10 however fits more like an 8 or Medium in my option. Pit to put approximately 21 inches. Arm pit to end of arm approx 16 inches and pit to bottom of the coat is approximately 21.5 inches.
