Oh, dear, mbmb, my apologies for misguessing - I thought I recognized your ID from another board. Oops.
So - I see a big difference in the "length" or "height" of the "handle" (so many quotes!) between the examples among those illustrated on mbmb's links. No sticker on mine, I'm afraid.
I keep trying to solve the identity crisis. Now am wondering what overall weight of the glass domes might tell us if surveyed comparatively. Not that precise amounts were taken onto the rod, or sheared off at the end of creating. But it's another data point, and might vary considerably by glass formula (or might not.)
