Front bead tap size

[6pt-Sika]

What tap size was used for the front beads ?
If it makes any difference the front bead in question is the type that kinda looks like a tiny air rifle pellet .

Original parker beads are a #2 screw size. Vs. 3-56 is the most common modern bead tap size.

I'm guessing you mean 2-56. I have no idea why I have it, but I just found a 2-64 tap.

As Brian said, 3-56. 6-48 is also a common modern size. I just found 3 of the 2-56 taps. Probably never use them.
