Age of a French Faience Desvres Double-Salt?

Georges Martel mark on base. Your thoughts on age?

Thank you!

 

This link to a site with French faience marks would seem to suggest without actually saying it categorically that manganese marks were 1900-1920 and blue marks were post 1920.

I'm sure that if @vitry-le-francois stops in you'll have a much more accurate answer. (Though of course someone else may know too)

 

Thanks so much, SIS! Much appreciated.

 

Rnwerner knows a great deal about this stuff; is he a member?

 

mmm...looks like it just not here a lot but maybe he'll stop by. @rnwerner

 

Yes, I believe it is Georges Martel. Pre-1922, before he move his factory to Longfosse.

 

Thank you all! Much appreciated
