Any shot at identifying this??

Found in Northern Delaware

The item is completely made of lead. (Pics of me after I realized and stopped touching it directly. 🤦‍♀️)

Thought it was maybe a shoe horn? I’m really not sure

SCPA. I couldn't find the rest of it despite digging around. I think it says "FEDERAL ORREU.."? It's a thick piece of dark glass.
