Sturmey Archer 3 Speed Hub 40 Holes Vintage Rare Fits Schwinn & Others. Stamped 723164 on it which stand for 1964 I believe? I’m not 100% sure. Used but it has been clean, checked and tested. Good working condition. There are still original Sturmey Archer sticker on it when I take it off of the original bike. You get exactly what show in the photo.
