French foundry mark?

Factual Questions
1

I have a pair of small bronze busts looking like a really incredibly ugly Napoleon/Josephine pair with an “Espie Paris” foundry mark.

The artist is “JB” “Beauvais” which one person identified as “Jacques Beauvais” who was not known as a sculptor. I checked in my Benizet, and the only remote match I could find would be “Jean-Francois Beauvais” who worked with bronze.

My surmise is that I have a matched pair of bronze busts of Louis I of Holland and Queen Hortense (they do not have names attached to them), ca. 1810, but that is pure guess at this point.

Can anyone aid me on this? “Napoleon” has an exaggerated bicorne with clear curves downward at the tips, worn in the French manner. “Josephine” has a huge hair-do, and an even higher bonnet (calash?) with hair nearly reaching her eyebrows. Both are mounted with clearly old hardware on turned marble bases, showing normal chipping on the bottom edge (what counterfeiter would even want to make this pair looking so strange?)

Any help, guesses, or whatever are greatly appreciated.

“J. B.” is almost certainly a Jean-Baptiste. A search for him in Google books reports a few busts and cemetery decorations cast in the late 19th c.

It would be nice - but “Jean-Baptiste Beauvais” was born in 1825 and died in 1892 , and the busts I have show fashions circa 1810, and the “JB” has neither hyphen nor periods (Jean-Baptiste appears to have used periods for both the J and B). The example of your Beauvais is a terra-cotta bust in a cemetery, which also seems a problem. Did you find any image of his signature so I could be more sure?

https://www.scholarsresource.com/browse/work/2144594054 does not give any signature data - so I am unsure whether the “B” is his last initial or a middle hyphenated initial.

Many, many thanks for any other info you might have - I had hoped the foundry mark would also help in dating these.
