Big tray from Lissabon

[huszas76]

Hello All!
I find this beautiful tray. I recognized, that's from Lissabon. But I don't know too much about the portugal silversmith's, and I don't have any source. So please, help me about the maker, the age of the tray and about the fineness if you can.
It's a really big one, 1907gramms, and around 40centimeters
It's stand in four legs, and each marks are in each legs.
Here are the pictures:


I hope, someone can help!
Best regards!

Those portugese of old used to be the law unto themselves. I have acquired some years ago , this enormous soup tureen, capacity 10.5L. The dealer told me that he has relieved his own mother of it and that it has been with the family "for ever". There were no hallmarks to be seen and I have spent hours trying to locate the island on its sides among the portugese colonial possessions. To no avail. Eventually I have had it assayed as sterling in London.

Just a few words of a post scriptum: the tureen providers name sounded very royal to me-Louis and for all I know the raided kitchen cabinet might have been of Dona Braganza or some such high and worthy lady. After all, those people do like the colour of our monies also. We used it only once in anger as you can work the sums out yourselves: tureen-ca 6kg if memory serves me well. Silver ladle-0.5kg. Soup liquid content-10.5kg. The english 100 tr oz solid silver tray-3.1 kg to carry this loot. Soon it does build up to some serious weight.You would need to hire two muscular les paisants to carry this soup into your dining table.However, may I refer to my previous musings upon the royal provenance of nepalese teapot? The items ordered for the royal household did not have to carry set of hallmarks. Royal person was beyond suspicion of peddling fakes.
