It's surprising what you'll find if you just keep your eyes open, all these off ebay and none where expensive. While these are stubs the same applies to flex nibs ( as long as you know how to pick a flex triumph nib... which doesn't have the indented line on the nib). I've been watching a snorkel with a damaged cap and a decent looking broad stub do the rounds ( at least twice) with an asking price of $70, the nib's worth at least $150. As an aside most Australian made triumph nibs are softer than their US cousins. As Karl mentioned fine appears to be the most common triumph nib followed by medium. Getting a nice little group together as well !!RegardsHugh
