The stainless one is a Navy issue jackknife.
Camillus maybe.
Look on the blade for a date, the value goes up as the date gets older.
Not necessarily Navy. Could be military, OR commercially sold version after war was over.
May say USA on blade and/or U.S. 45 on other side of the bail.
Not Camillus. Clearly says Kingston on it. Which would link it to Ulster and also possibly Imperial..........
