The only other things I can add are:
The book
Schneider by Edith Mannoni, does not include a main photo of any item with the "Love" decor. However, in the back of the book are several pages showing copies of "Reference pages" [company design records] and one of those, titled "Cloisonné", shows a ooloured reference for the "Love" decor. That page is indicated (perhaps by the author?) as being for items made "1925 - 1928". This ties in with the information in the Glass Museum article.
As for the metal stand with the "st eloy" mark, I have no knowledge of that other than what the internet tells me about Saint Eloy (or Eloi) being the patron saint of metalworkers.
Since items in the "Cloisonné" series are said, in the Glass Museum article ( * ), to be "extremely rare", it may be difficult to find a reference to any sales information from which a current value might be deduced.
I would suggest that the only way to determine a current value for this item is to contact a knowledgeable auction house or main dealer. Or, perhaps contact Mr Karman via the website linked below.
