material is particularly susceptible to breakage since

thing happened to my boyfriend's R13 Greenline about 8
years ago, and after the repair, the upper joint still
rocks a bit in the socket no matter what kind of cork
is used there."

I'm not an experienced repairman and can not say how
strong the Greenline material is, but I will make two
comments.

I've heard that Greenlines were prone to tenon
breakage when they were first introduced, and I've
understood from the new west coast Buffet sales rep
(and I apologize that I've forgotten his name) that
that breakage was due to machining of a too sharp
angle between the tenon and larger body, thereby
creating a place for a fracture to initiate. From
your photos, I see that your fracture did not start at
that point.

For your boyfriend's instrument's wobbly joint, search
for "loose joints" in the bulletin board archives.
Clark Fobes describes a trick with super glue that has
worked great on my horn. A small bead of glue is used
to take up the very small space between tenon and
socket that leads to the kind of wobble that cork
doesn't help. I don't know if this trick is well
known or used much by other repairmen.

Good Luck!

PS What a polite and well crafted response you have
written, Jen.
