> Dale, Apparently the Super Course was tacked with copper too. I had posted to the Framebuilder's list about finding copper residue under the paint and the chainstay bridge being (apparently) completely joined with copper. Below is the link to Brian Baylis's answer and my original posting: http://search.bikelist.org/getmsg.asp?Filename=framebuilders.10410.0187.eml
This was supposed to be a quicky paint job as I doubt this frame is worth a full resto effort. So it will have a paint job by me inflicted upon it. Just interesting what you find under the paint. Turns out the painters were pretty good as the "runs" or funny spots in paint have turned out to be brass rather than paint! To all the "un-brazed Raleigh joint" conspiracy theorists: This one has had brass peeking out of every joint uncovered so far!
