This is a large A. Lanternier, Limoges, France, antique meat plate.
This piece dates back to 1900, but Frederic Lanternier started the company in the 1870’s. In 1890 the son, Albert Lanternier took over the business, thus the A in the maker’s mark.
It is in very good, used condition. Take a look at the photos, you can see the dimensions of the pieces there. And, if you have any questions, please e-mail.
