I will take a close up as soon as possible of the shimmering red inside.
In the meantime, I ran across this link HERE
. Now I am only referring to this link due to the swirled and twisted base on the one there. It looks much the same as mine. Not saying that is the maker, as I guess (as stated here) that piece was made in 3 pieces.....so it is possible that *another* glass maker made the base, while the other was working on the other section
Anyways, I thought I would add this here -- merely for my Swan twisted/swirled base as to the one in the link....Hope that is OK. Will get a close up of the shimmering red later to post...
