Thread: How did she measure?

A bit ago I won an auction on a " 1 inch wide Geo Wostenholm, bone handled razor". I finally got it in the mail today and excitedly opened it to see what I would have to work with when I finally get moved.

The "bone" handles were badly outgassed (past tense) celluloid. holes all the way through. when I asked how wide the razor was I provided clear, explicit, easy to understand instructions referencing pictures, on how to measure the width of the blade.

I'm curious what kind of scale she used to measure the width.
