Id big Silver old Plate with 2 royal coat of arms and 2 signatures engraved

Hello everyone,

inside a lot of ancient objects that I won at an auction house in Rome (Italy)

I found this big old metal plate / plaque; it is not magnetic, I assure you that it really looks like silver.

But besides this, I found some very interesting things:

I found two heraldic / royal coat of arms engraved, and also two Signatures, but I can not understand as well.

At the center are represented two birds.

Diameter is cm 16

Through your help, I would like to understand what is struck, which country it is, and to date it if possible.

By the oxidation I could place it in the nineteenth century, but I am an expert in numismatics only,

so I entrust myself to you for a more professional opinion.

I thank you in advance for the answers

I wonder if it could be north african maybe Morocco

I think Islamic; Moroccan or even Indian. The decoration is too rough and too clean to be old, although it’s very possible they’ve used an old plate, hence the pair of marks.

Hello, excuse me, i dont understand the meaning of this phrase "although it’s very possible they’ve used an old plate, hence the pair of marks."

Thanks

From what I see, the crests are composed of a crown and laurels tied by a central bow,
and it does not seem to me that Islam, Morocco, and India have their laurels .

I have found some similar royal coat of arms here :

what do you think ?

could it be a coat of arms relating to an old Italian municipality?

Please if someone can help me more with this plaque, thanks
