It is a 'Yachtsman's kedge' commonly referred to as a 'Popeye anchor' after the comic book character, Popeye .
It was the anchor of choice for larger yachts prior to the development of the Danforth and other modern anchoring systems around WW11.
if you peruse the larger boats along Indian river you may see some still in use. However most have been retired and are used as decorator items in homes, restaurants and bars, so cleaned up it could have value,
I have four; several appear larger and one about the size of your anchor. So far after all these years I have not found a use for them, other than moving them place to place as a component of the yards décor
Some where in this board I made a post about salvaging a 7,000 pound yachtsman's kedge anchor off Catalina Island on June 4, 1960. It had been attached to a whaling ship that had sunk in late 1800s. The anchor was sold for $500.00, over a good months salary in 1960 and later donated to the maritime museum in San Pedro, where it will rest forever
I do not know what to suggest that you do with your anchor, but since they are rapidly scarce becoming antiques of days gone by, you just might want to hold on to it as a family heirloom
Hope this is information is helpful for you
