These are the brakes I bought for $20 on eBay. They even look more appropriate to the vintage.

Nice calipers, original Dura Ace. I have a set and they are actually about a decade older than your Raleigh and its parts. Those AGCs are more "period correct" if that's the kind of thing that appeals to you.
