Headset Bearing Size? Nottingham Raleigh
I was just wondering if anyone knows what size bearings the stock headset of a 1970's Raleigh might use? thanks
Do you have none? You can take a single bearing to the LBS and they can measure it with the Park ruler and give you a handful of sparkly new balls for a buck or two.
That's the best guess for a loose bearing (or retainer held loose balls) but I also recommend taking the old headset apart as you will need to confirm both the bearing size and the number of balls in each race.

Here is Sheldon Brown's article on Raleigh threading. Scroll down to the section on headsets:
Also, you might post this guestion in the C&V forum for more detailed info.
