I found one almost just like it today, only mine has been in a fire and melted on the very end. Mine seems like pot metal or something like, I think I could snap it if I tried. Camera is loaned out, but ill post mine tommorow.
I found mine here, there was a house there from the late 1800's untill 1921 at lest, but has been an empty lot for at least 50 years. I hope to find more.
Just started hunting it yesterday.
