I presume this is the adjuster that actually fits thru the hole in the arched centerpull brake support on the older raleighs, and is brass colored? This part can be really difficult to find by itself, as they are easily lost, and people who switch to side-pulls (such as on super courses, competitions, and Internationals) generally toss them out! I have scoured up a few, and hold on to them tightly, as I have a number of Raleigh frames which one day will want one! Sorry!!
