Featured Castelli ? large and heavy vase, dating mark

Hello

I would like to identify and date this large and heavy Italian vase,
it should be a "Castelli" but I can not define the date according to the backstamp
Live is really majestic and impressive.
height 46 cm
width 34.5 cm
weight 3,774 kg

Thanks

 

Sorry, I can not help, I just wanted to say you do a fabulous job on your photos

Maybe @Walter Del Pellegrino can help?

 

Thanks

 

great lookin vase !!!

 

I don't have any expertise here, but the pattern makes me think of Portugese items.

 

update: I found it, the logo corresponds to CASTELLI, in the province of Teramo, Abruzzo, Italy .

The problem that remains now is the dating,
an element for me fundamental for the cataloging of the vase

Is it possible to date it by the painting age or by the painting style ?

Thanks

 

I can not read the second one, but is either one of these active where you could email to and ask? Would also be nice to see what @Walter Del Pellegrino says, he is an authority on Italian ceramics.
