Interesting mark design

Recommended Posts

I have a lot of NF reports, but it's rare to find proof of destruction. This one appears to have been struck and cast aside when a fiber optic line was installed. I sent these pictures to NGS so they can mark it Destroyed. I'd never seen pictures of this pipe and spear point anchor design.

 

It is an aluminum pipe with the aluminum cap and point having shafts driven into the pipe and a rivet to retain the cap. Overall length is about 30 inches. It has magnets on the top of the spear point, but they are too deep to produce a distinctive response in a magnetic locator.
