That's a whole lot of clad! Nice old lock! People get a little weird when it comes to "pipes ". I was detecting on the beach and a guy came up to me and wanted to give me a silver weed pipe? Told him no he found it he should keep it, I walked away and he laid it on the sand, Ya, with my luck If I touched it I probably would have been arrested in a sting! He really wanted to get rid of it! Lol!
