Unlikely to be either; much more likely that Zimmerman bought the glass, added the leaf mounts, and sold the range as their own.
Connie — I can remember this query the first time around, and that several of us had seen both Bagley and Sowerby glass in these mounts. The ultimate leaf-mounted piece was the tulip lamp (aka cabbage lamp) of which I have seen just the one, in satin green, and only matched by the Leek Andromeda lamp as a retro classic.
