Hi Bernard,
Your supposition that the quotes mean that the name is "
a legitimate manufacturer name" is perfectly reasonable, but it could also, perhaps, be taken as implying that that was the authors given name. I haven't checked, but are other known, correct names in quotes within Liebe/Hayhurst?
As for your reference to brown, I remember a renowned collector who is no longer with us referred to all amber in a very derogatory way, with a particularly unfortunate four letter word beginning with 's' prior to the word brown :spls: :huh:
I am sure there are a huge number of collectors who would disagree with the word brown, let alone the reference I make, particularly since it can be so alive when lit well, but I do understand the point you make.
Lastly, the bowls appear to have the rings that were a registered design, I recall are referred to as '
Stratford' pattern. This will certainly help date the design, but the date they were made should be found through the style of the mark.
