Photos are the best description. I have added data on the photos. Please check them out. I obtained these from one fellow a long time ago. There is a paper item warning the Iraq military about USN attacks coming. So that kind of a start date—-don’t know about earlier or later. There is a really heavy cast brass plate and it shows what I believe is the Intruder. There is a great stamp on the back of the plate that you should be able to read—-mfg. I believe is in Washington state. There is a large metal triangle from NAS WHIDBEY ISLAND. No idea about it. Appears it was made for a unit plaque. There is a nice Zippo lighter with U. AMERICA / CV66 engraved front. So you will get all of what you see. I probably not be able to answer question about who, what, where, etc.
