Bonjour.

Here’s some pieces of information on your Daum vase.

As you see in an attached image scanned from Mainichi catalogue, 
there is no signature on the two vases with the drawing of Frühinsholz grand foudre.
So far, I have seen several same pieces with no signature.

Therefore, I presume the signature was not made originally (from the start) 
on these Daum vases commissioned from Frühinsholz.

So, your piece is a correct one without signature, as it is.
(It is better for you not to ask the artisan to put a new signature on it.)

The same piece you keep in the photo file  in your mobile phone
had the signature on the base. (The description was so written.)
But, I presume the signature was put after by someone.

Unfortunately, the same vase as yours was sold at 260,000YEN
at Mainichi Auction in 2014.  
That is 1940EUORS, too far from your price …

Bien cordialement,

YAMANE, Ikunobu


P.S.
I made a mistake.
The grand foudre by Champagne Mercier was for 1889 Exposition Universell,
not for 1900.
It was another one. (See an attached image.)
