Thanks to all for the continuing comments. These kinds of threads are extremely helpful and are one of the key resources people will be able to use to help identify paperweights.
The posted photos of the signed Schneider contemporary American paperweights have a signature dissimilar from the one I and another member (Mark) have. And I think I can safely say that the pedestal is older and of a completely different glassmaking style than the more modern weights shown in the posting. Our signature has more of a formal template appearance - as if a mold had been made of the signature and then impressed faintly into the glass. But with his comments, Frank may have taken that "mold" concept out of the equation.
I am going to post a reference to this thread on the Murano Board and hope that Murano collectors will take a look at the photographs and commentary.
I am very interested to know that a needle-etched signature similar to the one I have is attributable to Schneider from 1918-1930 as Frank has posted.
Somewhere, somebody was making these paperweights and people have them in their collections. In fact, because of the faintness of the signature on the bottom of the smoothly finished and highly polished base, there may be many others who have these pedestals and have never actually seen the signature.
I'm also posting another, albeit sharper, image of the pedestal weight to help in the search.http://i4.tinypic.com/zx3bd0.jpg
