It came a big ole honking needle - not a 15X1 size needle. I assumed the needle was the elusive and almost unobtainable Boye #10 or #20. How would I verify that? I would love to sew with her but wanted more than one needle before I began a project.

Chris,
Here is a scan of a Davis Long ( Boye #10) needle besides a rule and a 15x1. You can see the big difference in the length of the two.
ISMACS has several sections on needles, specs, and such that is worth the time to study.
