I don't have the time to spend prowling eBay and GB. Would that the folks here who put this stuff up for auction could give us a heads-up when they do, please. I did luck into discovering this treasure trove yesterday thanks to this thread, and scored a steel grip cap that came from MP's stash. (Probably paid too much, but like Steven said, sometimes the provenance of the part makes it more special/valuable in my mind.)
