It's a bit devious, it gets an awful lot of DNF's from newbies. By all means have a look, but get a bunch of finds under your belt and you'll find this much more easily
It's a nanno, bring your pen and tweezers.
Please note, you do not have to dismantle anything, when you see it, it's there for the taking, please don't prise the endcaps off the metalwork, it isn't there.
Before you grab it, LOOK WHERE IT IS AND PUT IT BACK IN THE SAME PLACE!!
Congratulations to BowenTribe for first to find, commiserations to Squinty 1985 on being pipped to the post!
