They are found here too, seems that a lot of the more common English bottles are common here too.
They are still a nice looking bottle the Kepler's, someone posted a photo of a green one on here a while ago too.
I don't know what was in them but the one I found with a bit of bright blue stuff in it killed the grass on the spot I cleaned it, dunno what the stuff was but it was not the Iron Ferro-Cyanate I thought it was [X(] .
