B&H/Besson 1980's question for English repair guys or Americans who just know it anyway

Pertaining to those old 1980s tiny little Boosey & Hawkes B-flat tubas with their crummy looking little chrome plated finger buttons..
What thread size were those finger buttons, please?
(I have to replace them with something, and don't look forward to running a tap into their valve stems.)
Thank-you gents.
