Sorry for the loss of, Emil. I actually know a guy in Canada who makes the most beautiful Artillery shell urns. Last I spoke to him, he offered brass 105MM Leopard Tank cases and brass 105MM Howitzer earns. His primary trade is fabricating brass cannons and is a master craftsman. I met him while trying to locate a 105MM Leopard Tank case. for my collection Anyhow, he turns a beautiful solid brass cap with screw on top for the urns on a metal lathe, then polishes the entire urn. If you have not already found what Emil’s family is looking for let me know and I can send you my contacts direct info. Again, very sorry.
