I've great respect for the knowledge of the other contributors to this thread, all of whom have probably forgotten more about pressed glass than I shall ever know - and I made it clear that I was unable to help with attribution/provenance.
Unfortunately, I truly do not understand what lies behind Sid's comments - there seems to be a lack of explanation - what it is that we have done that is so wrong. Has the Board previously made it clear that items on a certain selling site could not be discussed until after the auction was completed? I don't recall that particular topic - and why is that that selling site is now not mentioned by name? If there is some genuinely unique reason why this item should be off limits, then a proper explanation is owed at least out of courtesy.
quote............. "I have had at least one auction directly and adversely impacted by a similar posting on this site. At that time, I expressed my thoughts and still feel the same way".
Is Sid suggesting that in the past GMB members have commented inaccurately on something in which he had a vested interest, and this has cost him a purchase/sale?? What specifically is it that we have said so far that might be harmful - isn't the purpose of the GMB to promote further knowledge of glass and to discuss openly the accuracy (or otherwise) of attribution/provenance.
Fred states that he has permission to use images of this piece, and comments that a Soweby attribution has been originally provided by the owner, although it appears that presently confirmation of that remains to be provided. Is there a need for secrecy in this particular instance? This lidded jar may be a Sowerby piece, but in the absence of confirmation then surely a discussion on the subject can only be helpful. Of course, if someone is deliberately withholding information (for commercial reasons), then that is to be deplored.
Understandably the Mods/Board quite rightly do not permit libelous or potentially litigious comments to be made in reference to individual items on internet auction/selling sites - is it being implied that we have we been guilty of that in this instance??
Internet auctions of whatever nature are rife with inaccuracy and mis-attribution although most of the time we can do nothing to correct that, so from where I'm standing it can only be a good thing to discuss the validity/history/provenance of items with a view to providing better and more accurae knowledge for all. However, if it's personal interests that lay behind these euphemistic comments, then that should be clarified.
It appears that I may have mis-understood the aims of the GMB, and if so then this is not the place for me, and I thank those sincerely who have helped me over the past few years, and wish everyone good luck.
