Peter,

It may not be as bad as you think. That stuff ratteling in the tube is most likely hardened flux left over from brazing. I would try drilling a hole in the seat tube from behind the seat lug with a long drill bit. should be easy to do through the slot in the seat tube or the hole that (is hopefully) at the end of the slot in the seat tube. The hole does not have to be very large; 1/8" should do it. Then, squirt some grease into the top tube to which the flux balls will stick. That should do it.
