Allan, aren't the butterfly examples of modern production? I though that the dragonfly was vintage 1930's due to the type of scrambled ground. A vintage 1930's butterfly would be pretty scarce too, I would think.
Tropdevin and I had discussed this weight when it was first listed becaue of his upcoming article on Chinese weights in the PCA Bulletin. I had thought that it would go at the $400 level, but that was obviously a bit off the final mark of $1100.
