I have just bought yet another Bernsdorf
Evelyn vase, not for resale, but for use, as it is, in my not so humble opinion, the best and most idiot-proof flower vase ever made. See the bottom of Pamela's web page
here.
It was obviously a close copy of Davidson's unregistered 278 design, see
here, but instead of being fitted with one of Davidson's rather difficult to use styles of flower holders, it was fitted with a close copy of the excellent Sowerby unregistered
Derby flower holder, see
here for an example. The
Evelyn vase was improved by providing a locating ledge to ensure that the flower holder locked into position (although Pamela's photograph as of the date of writing shows that you can locate it at a strange angle if you really try!)
So, the question is, who designed
Evelyn?
I think it was more than likely someone in Britain who may even have tried to get Davidson and Sowerby to cooperate on this, and, in frustration, commissioned Bernsdorf to make it. Possibilities include Bersdorf's agents in London, and major factors like Lang.
Are Bernsdorf's agents and other business associates in Britain known?
Bernard C.

ps — How is/was Evelyn pronounced? There seem to be two versions in Britain — ever-lyn and eve-lyn. How is/was it pronounced in Germany?
