Thanks for clarifying this. Now that you mention it, it starts to come back. My memory of the details of that era are getting a bit fuzzy. IIRC I bought a set of record brakes around '82 that still had steel holders. Alloy must have been introduced after that -- probably around the same time as those dumb alloy toe clips and revised shift levers that didn't work very well.
