Sad but the receiver will probably have to be destroyed. Can you have something like this dewatted in the U.S.A.(deactivated war trophy)? Here in Canada
I think they can be rendered permanently inoperable, inspected by the RCMP for proof and you are good to go. Still some value in DEWAT machine guns from the prices I see on Canadian forums. It is a crying shame to see history hacked up and melted down.
