The article in the PCC Newsletter (issue 89, Dec 2005) was written by Bob Hall and showed pictures of the "pink" ewer and a yellow one. In the previous newsletter (issue 88, Aug 2005) another one, with a "milky white" ground had been discussed. The "milky white" one was the one that I would have bought had I known about it early enough!
Strangely (brain cells giving up??), I only half recall the one at the Perth Conference. At least, I remember taking some photos, but as yet I can't find the pics. And I can't find my pics of the "milky white" one, either!!
In Bob's article he said, in one part, "Attribution could well remain a mystery for a long time". Later in the article he commented that cane matches could be made to Harland period weights. It was also pointed out that it had been suggested [which I had certainly done, when I discussed these ewers with Bob] that some of the canes in Harland weights could have been from the early years - or very similar canes pulled during all of the years from the 30s to 70s. Bob's view was that with many matches in the ewer canes to those seen in Harland weights, then it was more likely that the ewer was from that same period.
In the Issue 88 article, the owner of the "milky white" ewer commented on my fluoresence test and cane matching [although only one cane could be definitely matched at that time] and we both concluded it was "Vasart or earlier" - but the article image was titled "Monart Water Ewer". A particular feature was that the clear glass foot and handle showed the well-known purple tint of many early Ysart (Paul & Salvador) weights.
My view is still as it was, with a preferred attribution of: "Vasart 1946-c1955 or perhaps 1930s Monart period". But who really knows?
