I also posted this in the vintage forum, but it was suggested that I post here too.
I just picked up a second Raleigh Twenty yesterday, and for the most part, the bike is stock and in great condition.
One problem though:
At some point in the bike's history, someone attempted to improve the steering by replacing the nylon-bushing-and-chrome-cup setup at the top of the steerer tube with a bearing race. It seems like a good idea, in concept, but that modification has only left room for one of the nuts that holds the fork on (no room for the Raleigh headlamp bracket either- neither of which were included with the bike). This is a problem because the mere act of steering the bike will loosen the nut and compromise the bike's safety.
I'm more interested in restoring this bike to factory goodness by replacing the missing parts than I am in pimping it out with a modern headset (I find the stock setup to be adequate for the type of riding I do).
I'm interested in finding a replacement for the missing steerer tube nut (the larger one- I imagine it's 26tpi, but not certain), the missing nylon bushing, the missing chrome cup that goes over the nylon bushing, and a Raleigh headlamp bracket.
Does anyone know where I can find these parts? I know the headlamp bracket shows up on eBay all the time, but the other parts seem to be slightly more exotic. And since I'm asking, my other Twenty is missing the seatpost bolt and L-nut. I'd like to find a replacement for those too (a long shot, I know).
Here's the bad setup:
Here's the good setup on my other bike:
And for illustrative purposes, here are the parts I need, highlighted:
