Vintage Pringle of Scotland Beaded Cardigan Sweater Size XS/Small?

Good vintage condition. Feels like it could be cashmere but there is no tag indicating. There are a few holes that can be seen in closeups. There are also some color variations? that I tried to show in closeups but I’m not sure the camera picked them up. Top 2 buttons are missing.
No size or fabric content tag. Based on measurements, I believe it’s an xs /small. Laid flat, pit to pit measures appx 28 inches and length is 20 inches. Shoulder to shoulder measures 16 inches and sleeve length is 24 inches.
Beautiful beading at neckline, sleeve cuffs and around chest pocket.
