Antique Wright Soc Anon Silver Sauce Gravy Boat Plateado Sobre Metal Blanco

Description

I'm no expert when it comes to silver, and I have no way of testing it, so what you see is what you get here. :)
I did put a strong magnet to it and there was no pull, I also took a pic of it on a scale if that helps.
Another one of my pics shows the marks on the bottom that say Plateado Sobre Metal Blanco - Wright Soc Anon Argentina
I can't tell if it is silver, or silver plated, so please do your research before bidding, as well as inspecting my photos. Thanks!
8" front to back, 4" to top of handle
