Shetland Wool Sweater Black Vintage Turtle Neck No size Tag Maybe small

No size tag but the venue makes me put in a size. I am guessing maybe small. I am not sure of the age of this sweater. It is at least 30 to 40 years old as far as I know. Maybe even older. Could be worn or could be unraveled and the yarn reused. Please, see all photos for more details as they are part of the description. Comes from smoke and pet free studio. Approximate measurements are laying flat. Chest - 16" Length - 24" Sleeve - 23" Shoulder - 16'
