This is the Danforth anchor that came with my boat when we bought her in 1997. I have no idea if it was original or not. I replaced it with a 45 lb CQR I picked up, only because I thought this anchor was a 35 pounder.
But, when I was swapping them out, they weighed about the same and there is no weight marking on the anchor. It simply says "Danforth 5 - 1"
It had been galvanized, but there was rust on the plow tip where it had dug in and scraped off the galvanizing.
After removing it from the boat, I brought it home and used a wire wheel to remove all the rust I could. I then spray bombed it with an ani-rust zinc paint
