This lot of historically significant flatware comes to you from the estate of our late Aunt and Uncle.  Members of their family served in WWII, Korea and Vietnam.  Not being an expert on militaria, I can't tell you from which period these are from.
The four forks measure approx. 7-1/8" long.  Each is marked "U.S.N." (United States Navy) on the handle and have the "Reed & Barton" stamp on the reverse side.
The knife measures 7" long and bears the maker mark "Silco Stainless".  The face of the fork reads "SECOND'S" and the back reads "MIDSHIPMEN'S MESS".
Overall good condition w/ general age/use wear.
