Vtg NYPD Crewneck Sweatshirt Cropped Fit Blue Sweater S/M

Vtg NYPD Crewneck Sweatshirt Cropped Fit Blue Sweater S/M i believe made in USA originally tagged large but measures 24.5x21.5, wide boxy but fits short honestly i dont know anything about this, have been unable to find a single listing online or even any of the same style of sweatshirt. It looks and feels very old, I'm guessing 1970s but dont know for sure! if anyone has any info pls let me know the sleeve stripes stitching has become undone in many spots leading them to be more loose strap like. these can be easily repaired by a tailor or yourself just a quick straight stitch
