I just picked up this 1971 triumph. I would have been 14 when the hub was made. 2-71. First time I have ever found a reasonably priced English 3 speed in my size.
23" for 35 bucks and while rusty and with a loose headset, everything works. Unfortunately I lost the oil cap to the hub. It was a plastic one so if anyone knows where replacements are, that would be great.
