Old English Poole Covered Dish with Handle

Vintage serving dish. Nice vintage condition. Handle unscrews so could be refinished. It looks like it needs oil or varnish. Pan is 10 inches across including the decorative border. You can see mark on bottom in photo. It says OLD ENGLISH BY POOLE 5030. Cover has ornate top handle. I don’t know metal. If I guessed I would say silver plate but do not know. I do not see a metal identifying mark. Vintage Vintage silver pan Covered pan Covered serving dish Serving dish with handle Ornate
