I'd leave it as is. You can buy a non dug 2 tine fork pretty inexpensively to display with it. BTW, even though it was found on a CW site, the fork is much, much older, probably made about the time of the Revolution. The 3 tine fork was invented at the end of the Rev War and was popular though mid 19th century, when the 4 tine took over. Remember, the guys going off to battle did not bring the best stuff from the house with them, but the older items their folks could spare.
It's a nice find. They are not found that complete often.
