My statement was probably too apodictic

Murano glass is such a wide area...
On the other hand, my first thought when seeing a base finish like that wouldn't be "top Murano"

@John: I only ever saw 3 AVeM "anse volante" pieces live, and they all had properly polished bases.
Even in the mass produced tutti frutti range, only the dainty toothpick holders and small vases seem to come with unpolished bases; all bowls I have seen so far, and my big vase have a nicely finished base.
@Nic: to find a roughly ground base on a "Scavo" piece wouldn't surprise me that much.
My SVdA pieces have the most elaborate base finish in all my collection.
Can you show me a crude finish on a non-Scavo piece?
@Trevor: Frank is one of the most knowledgable glass people, and a member on this board (nickname "Frank"):

I am curious if we find out more about the maker of these pieces...
