Martyn, I agree. I too suspect a copy of the Tobago design by person/s unknown... the irritating thing is that I'm sure that way back when I first found the GMB and before I found this bottle, I saw them for sale on a website - in two colourways, this one and a peacock/blue/clear one. I've never been able to find that site again though... how irritating is that! :hb1:
