Stumbled across this last fall...
We'd seen it in a field next to a small shack-style restaurant...tried to buy it from the owner...he wouldn't sell.
A couple of months later...he went out of businesd...shame because the food was good.
New owner was there clearing the field...we stopped and asked about the anchor. "If you van get it out of here in the next 30 minutes, you can have it.
Fucker weighs 400-500 lbs, so I ran to the local lumber yard a couple of blocks away. Their yard manager brought their delivery truck and forklift...loaded it and hauled it to my house. When I asked how much I owed him...$20.
I handed him $30...and thanked him.
As near as I can tell, it's an old US Navy landing craft anchor. There was USN training base up the coast a few miles from here...BUT, it's a Danforth anchor, not a traditional "Navy anchor," so I'm NOT 100% positive of its origin.
Oh...the chain is just an old log boom chain that was attached to the anchor...it's not a real anchor chain.
