Reposted Two old metal pipe detectors see description (Harborne B32)

Hi all, i am reposted these due to non collction. As you can see in the photo, these are two metal pipe detectors that have sat on a shelf in my garage for years. I have no idea if they are still working or not as I do not have any battery’s to try them out with but I thought I would check if anyone wanted them before throwing them out. Kind regards Eric
