I remember having a lacquered one for drinks and an unlacquered one for the Trangia meths. I've still got my drinks one, though it is battered, dented and scarred by being my chosen water bottle on nearly every hill and mountain I have climbed. Quite what happened to my fuel one, I don't know.
I also have one of their black, stainless steel, oval-shaped ones that they produced with a matching cup as a run of retro Swiss Army kit a few years back. Now that is a thing of genius and is almost always in my everyday pack.
