There appear to be variants made by various firms but I believe that mine and the one shown at the top of this topic by Bryn were made by Ravenhead as indicated in the original topic. The base is the same shape and texture pattern as a known drinking glass range made by Ravenhead (whose name I forget but I have a picture of somewhere!), and as a large manufacturer of machine-made glass Ravenhead could well have exported these all over the world, so finding them supplying a Tiki bar in Hawaii would be no great surprise.
