Thanks everyone. Michael, I'd forgotten, Richard Uhlemeyers name did come up in connection with this one. More known for his pottery than glass. I wondered, though it looks '50s, because of its thin base (hard to get a photo of as its so dark) if it could be earlier, it has an older 'feel' to it to me & if it were whether it could be described as Bauhaus in style?
Sue, the colours an unusual muddy red, i liken it to a blood red glass vase 1/2 filled with blood, gruesome but it looks like it

. The base, as seen in the photo, can have a slight pink irridescence, but the vase doesn't really look pink at all.
