That's the piece - first link is fixed now.
There may be no pictures in that thread, but you can establish quite a bit from the description. For instance, if I'm reading it rightly, there seem to have been two ways of making this bluerina effect - one involved casing or flashing the amber glass with a layer of blue, and the other involved a heat-reactive technique, heating and then reheating the top at the glory hole to strike and then re-strike the top half, which would change from amber through red to blue. The reactive element was gold. Does yours appear to be flashed, or restruck?
If bluerina really is re-struck amberina, you might be able to find a match in amberina.
