Yeah, wish I had, but I had not planned on building a bike with a threaded front end at that point.
In fact I wish I had bought two, £16 a pop was a better bargain than I knew, if £60 is what they go for NOS.
Still, I may just have to fork out someone's asking price for a headset at some point, as finding a decent threaded 1 1/8th is difficult these days.
