Shiny silver leaf 50s-60s vintage Royal Winton English china dish
Shiny silvery lined china leaf shaped dish, mid-century vintage Royal Winton - England. It's 11 1/4" long end to end.
This does have quite a bit of scratching to the silvering from use, which isn't hugely noticeable because the finish is so reflective. (The dark spot at the far right in the first photo is the camera showing in the mirror finish - not a defect to the finish.)
