Hello Wolfie, and welcome to PA. I, for one, would be interested to see any pieces you have found. I have family in London and a sister who enjoys mudlarking in the Thames. Amazing, the things that she has found over the years. More common pieces of pottery, pipe bowls, and such...but, also a jewel, Roman coin, and a flint tool. I'm always curious about the subject of stone points and tools from the "Old World".
