Actually, I posted after going to Bikes Not Bombs here in Boston. They ship used bikes to various
poor parts of the world. They save some of the better parts of the bikes to sell for financing their
activity. One of these days I will post a picture of their bike pile - at least 3000 bikes last time
I saw it. There is also Broadway Bicycle school that has an inventory of used parts, but they always
look to me to be picked over. I donno of any other bike shop in the Boston area that has a good
selection of vintage bike parts.

I don't recall seeing anyone selling older adjusting barrels on ebay. I have see boxes of parts
(for example see here http://sporting-goods.search.ebay.co...sassZsuesmccoy),
but nothing like the above. Perhaps I am not looking hard enough (reading ebay listings is my
prime way of avoiding work).

I checked the Yellow Jersey website, didn't see anything there.

It seems like this is a common enough problem, there are lots of old raleighs out there. I a little
surprised that there are some approach to this problem.
