I have a piece marked Wayne Filan 1970 London, I know he was at the RCA then, on a studentship, I beleive, but I don't know where he was in '74.
Could the first mystery word read "Budapest"?
I think Michael Harris went there in '64 to study some techniques.

(I've lost my book somewhere, so I can't check for accuracy right now. I know it was '64, I'm not absolutely postitive about the Budapest. Geography isn't my subject.)
Rubbing a little talcum powder over a mark with your thumb can help bring up a signature or writing for photography and better ease of reading.

I think you might be in the wrong forum, I think this one is for paperweights. I'll ask a moderator to shift it to general glass enquiries. Don't fret about it.
