ISO: 1" Chrome headset nut and some spacers
Found a neat old Puch mixte frame, in my daughter's favorite color, purple. Going to build it up, as a city bike, around an 8-speed Sturmey rear wheel, and a generator front.
Came with a smooth turning, chrome, 1" headset, but oddly missing the top nut and spacers.
Can append a photo, if helpful.
