Re Pen Cap Specification For A Sheaffer 33 Or 3-25 And A Waterman’S Ideal #2

[farhanc]

Hello

I have a question I am making 2 Franken pens using 2 vintage nib
Section 1 Waterman’s Ideal #2 and 1 Sheaffer 33 or 3-25 nib. I need
idea on minimum size for my cap section of pens. I have spoken to a
person in Florida who makes Sterling Silver pen parts. I need to know
diameter of the caps so I can order bands for the caps for my pens.

What I am looking for is diameter of the original cap that waterman and Sheaffer used so that can I can tell the silver parts manufacturer what dimensions on the caps are at their widest part. The band will be 3mm-4mm thick.

Also artistically what would be a good band thickness? A thin band or
thicker band.

Any help appreciated.
