Hi Tony, I have n update for you. While looking for a fake or repo mark of a RS prussia stamp on a item I have I came across an identical who have here. The website is PM&M (porcelain marks & more) then click on Fake & Repo marks. Scroll quite a bit and it’s on the left. It’s a fake mark for Sevres and Vincennes. Even has the H in center with the little blue dot’s. Don’t feel bad my item is a fake also even though it’s beautiful but I got it cheap also at a sale.
