Help - Tuning Lever Tip Size

[rggriff]

I have a 1900-1910 Collard & Collard upright which I'm trying to tune.
I have purchased a tuning set which in cludes a #1 tip which is too big
and wanted to know if a #0 is correct or if there is a special size for
adjusting these pins. The last thing I want to do is destroy a pin by using
an incorrect tip.

Thank you in advance for your help.
