I purchased this on an auction site previously. It's supposedly 100% wool, but the "cots" text suggests it might be an item for an old public service organization, as there are no specific markings. The previous seller mentioned in their product description that it might have been issued as a winter jacket for civil servants in an old Spanish transportation agency. When I tried it on, it feels like 100% wool, but I also have a slight feeling that some synthetic fibers might be mixed in. If you're concerned, it's best to refrain from purchasing. Personally, I was drawn to the "vintage black three-button jacket made of wool" aspect, which is why I bought it. So, I think it would be easier to judge if you consider it as such a jacket. There are no noticeable scratches or stains.
