Vintage 70s? Jaeger Brown Wool Button Up Sweater Jacket Point Collar Size 38

Vintage 70s? Jaeger Brown Wool Button Up Sweater Jacket Point Collar Size 38. Very good vintage condition. No pilling but there are a couple of small imperfections in the knit near the button placket - shown in photos. Tag size is 38 but pit to pit measures only about 16” across. Based on how this fits the mannequin I’d say this is similar to a modern size small - maybe a medium, but please refer to the measurements to ensure fit. Based on the brand label sewn in the garment, I believe this is from the 70s.
