I've got a few adjustable nib Dorics, and tonight I was restoring another one when I started to wonder just how many adjustable nib sizes there are. I have a #3, #5, #7, and #9 in my collection, and I know there are also #6 and #10 nibs, but a search for ads and pictures already online only confirmed those. Were there are any #1, #2, #4, or #8 adjustable nibs? Thanks!
