German Silver Charger 18th/19th Century?

[dw171]

I bought this at an estate sale. Its 13.75" wide and very heavy. Its engraved on back 3 4 13, which I think might be April 3, 1813. It has a partial city hallmark. I think its crossed keys or axes with crown on top. Maker's mark looks like MA or some combination or WV. Does anyone recognize the maker or city mark? It should be around 800 silver correct?

Rom in Italy?

Yes, it is Zappati Giovan Paolo (1726-1758) or his son Pietro (1759-1781) Rome.

P.S. The numbers represent the wheight in ounces

[dw171]

wow thank you both. I've never seen Italian silver before the late 19th century with the more typical hallmarks. can you explain how the numbers correspond to the weight? it's 40 regular ounces.

I think it's 3 libbre 4 once and 13 denari, it means about 1145 grams.

Thanks, its only lost a few grams of weight over the years at 1138 grams.
