Really nice find. I think you made your money back in the stainless alone. It's not often you find an object with three high(er) value metals and a lack of significant amounts of shred steel.
It’s waveguide and not plumbing. Possibly used by TV station for combining analog and digital transmitters when they ran both in parallel. Search for “Anatomy Of A Megawatt Upgrade” at thebroadcastbridge for an image of something similar.
I just scan a handful of auctions sites with items that are within about 50 miles of my house! Hopefully going to be getting a bunch of cool items in the new year
Its actually still sitting in my garage! I thought I could use it on a project in the future for something.... Im still trying to figure out how to use it though
I just have a bucket of hardware from everything I scrap, and when it’s full I’ll bring it in for scrap steel value. If they are brass or copper I separate them 👍🏼
