Raleigh Headset Bearings

[FONT=Times New Roman][SIZE=3]I have a late 70’s early 80’s BSA “The Prima” (Raleigh) bike and wonder if anyone can tell me what size the top and bottom headset (loose) bearings are likely to be. It’s a 1” threaded headset and was only a cheapish bike even when new, so shouldn’t be anything exotic.[/SIZE][/FONT]

[FONT=Times New Roman][SIZE=3]I stupidly thought that replacing something as simple as the bearings would not be a problem, so I didn’t bother to pick them up when they all fell out and now I can’t find any of them![/SIZE][/FONT]

[FONT=Times New Roman][SIZE=3]This is my first bike rebuild and I should have known better than to assume anything, bearing in mind all the other weird sizes on old bikes, not to mention Raleigh’s own take on things.[/SIZE][/FONT]
