It is also stamped (somewhat more crudely) on the back of the socket. CHG LL followed by what looks like a "registered trade mark" ("R" in a circle) though it is absolutely tiny. Also marked 8 in a different script on the side of the piece. It doesn't look as if it has been very heavily used.
There is, however, a small crack at the bottom of the socket. This extends a little bit past the ornamental silver band, which appears to contain it, so it shouldn't cause any problems. The very tip is slightly "nibbled" which doesn't cause any playing problems, so I have left it "as is" rather than polishing it out.
I don't like messing with old (and possibly important) mouthpieces if I can help it!
