Too light to be lead. High pitch ring when struck with lead ingot. Has to be better than 20-30 yrs old. Was in the back of gramps garage. I am thinking zinc? Maybe sacrificial anode? We do not live near salt water however. https://uploads.tapatalk-cdn.com/201...e660a7463e.jpghttps://uploads.tapatalk-cdn.com/201...4d5128279b.jpg
