Hello,
The 'person' on W/F's dot com was me. My version is cut and from the 1930's. I thought what I said on W/F's dot com was fairly explicit. The drawing for my bowl is held in the MoL archive.
Since yours is my one's blank, I would venture to suggest that it must be Whitefriars/Powell.
The person who voted 'No' on W/F's dot com's 'Is it?' must not have the experience, or knowledge, required for an informed view on the bowl - or else they just looked through the catalogues that are available online, which ain't all of them

PS. As for polishing, that is a decision that any dealer (or collector) in glass has to make regularly and depends on the individual's outlook. N.
