Collectable WW II USN US Navy Butter Knives Silver-plated Marked WA Vintage

WW II USN US Navy Mess Hall Butter Knives Silver-Plated Marked "WA" Set of 7 Vintage Collectible these look just like the Silco ones, which are the stainless steel ones, but these were VERY tarnished, and I have polished them. see the one knife with the metal worn, and you can see the layers, possibly copper or bronze engraved with " U.S.N. " on one side and what appears to be WA on the other, see pics purchased over 20 years ago cutlery flatware
