Dave — I'm not the only person to recognise and attempt to document Walsh, and particularly Walsh
Vesta Venetian. All my musings here have been in relation to what I believe is the later style made from temperature sensitive opalescent glass and not iridised. I have only had two or three examples of the apparently earlier Walsh
Mother of Pearl style through my hands, and did not record them. The best illustration of the two styles is on Philip & Anne Petrides' greatglass reference pages
here. For the benefit of new readers, Walsh
Mother of Pearl has no relationship to the US collectors' term for air-trap, explained in more detail elsewhere on this discussion board.
I think a Walsh attribution for your little lampshade is unlikely. That rim crimp doesn't look particularly Walsh to me. Also I've never seen
Vesta Venetian ribs break apart in the complete way they've done on your piece when blown to shape, leaving those pointed oval windows. Every example of
Vesta Venetian I've seen since I started counting has had the main element 18/18. I've never seen any Walsh piece made using a 13 rib dip mould, indeed yours is the first example of any glass I've knowingly seen made with a 13 rib dip mould. And, finally, it just doesn't look like Walsh to me.
The general technique of rib, twist, and rib again is and was widely known. When I took an example of
Vesta Venetian to Murano and showed it to an old-timer demonstrating glassmaking, he knew exactly how it was made and demonstrated it there and then. Only within the last few days an attribution query has come up on this board for a piece made this way, see
here.
The colours I've found so far of the opalescent second style of
Vesta Venetian are ruby, blue, green, white, canary, and the temperature sensitive orange, discussed recently. For a selection, see the penultimate photograph by Leni
here, top shelf, centre left. The white flared goblet vase behind the orange tazza is actually ruby!
I hope that helps.
