Hello I'm fairly new to the collecting side of the pipe world and in an estate lot I bought there was a Pipe stamped "Marks Square". Also says made in England and the number 347. I've googled it to death and can't find anything. It's a great smoker and I smoke it while mowing but if it's worth more or some rare antique may not go so rough on it.. oh and it's a sandblasted?? Straight billiard.
