I had a wheel built up using a 40 hole AW hub and 15ga spokes for my Raleigh Super Grand Prix that I converted to pseudo club bike. The wheelbuilder(owner of my LBS) decided that the thin steel flanges would be hard on the spokes so he used the brass spoke washers. Have only a few hundred miles on but no trouble. Looks like "Bike Tools etc" has them at a better price than QBP.

Note: The 15ga spokes were my idea for appearance sakes. He suggested double butted due to load they would carry (me) but relented since after all there's 40 spokes I reasoned. In Craig's case the damage may be done and you'll have to rebuild with new spokes.
