    On discussing this problem in my 1960s Mt Vernon Strad with my repairer he said "Do it yourself" and lent me his expander overnight, the brass was so hard I had difficulty in getting enough expansion, on a 1930s English Besson whose 2nd valve slide fell out the brass was so soft that I over did the expansion and had difficulty refitting it.
