Topic: anyone recognize this: two birds on branch: vaseline glass

[mrvaselineglass]

I got this piece a while back and just got to thinking about it.  Anyone know what company might have made it?
the two birds are vaseline glass and amber glass.  The branch has a layer of smoky gray under the crystal.  It is quite heavy.  It measures 12" to the top of the tall branch, and branch-to-branch, is about 10 1/2 inches.  I have seen one other of these, so believe it to be a regular production item.  Any help or suggestions are always appreciated!  It is my biggest (and most eye-catching) piece of murano vaseline in my collection and would sure like to know.
