I would like to pass on to the group a source for brass tubing which I
received in response to my request for tubing to use for piccolo pipes.
They put out a real nice catalog, free for the asking, and listing round
as well as other shapes of tubing in 1- and 3-foot lengths.

I believe some hobby shops carry this tubing if you are lucky enough
to have one in your area which is well stocked.
