Great looking anchor. Congrat's on a nice save and Best of Luck to you in its preservation. Just to throw another idea of preservation in the mix, research the product GEMPLERS. This is a product that can be brushed onto your anchor once you have it cleaned to your satisfaction. This product penetrates the iron and treats and preserves the iron from the inside out. I have used this on my 12 pounder artillery shell and shell frags and was pleased with the finished results. It would give the anchor a nice finish and show the details in full. There are some videos on Utube that show this product also. Just a thought. Again, best of luck.
