That would be the Gulf War - Operation Desert Shield/Desert Storm
(2 August 1990 - 28 February 1991).
It’s a Carlos 5-string banjo, serial number 15651, with two strings remaining. Made in Korea in the 1970’s to early 1980’s. 
I hate to put Banjo Ben brand strings on it, like putting lipstick on a pig.
It also has some other minor repair issues, so I figure this is my chance to go to luthier school! 
Ah so NOT a Gibson!
I too have a Pre War Banjo. My Pre War is a 1920’s Windsor Whirle Emperor Supremus 5 String Banjo with channel concealed 5th string. So I have five tuning pegs on my peghead with the 5th sting in the centre.
There is nothing wrong with putting lipstick on a pig. Just don’t go kissing her. You don’t know where she has been troughing around.
I am thinking once you get some strings on her she wont sound too bad. No not the pig the banjo!
From the pictures, it looks in pretty good shape.
Yep the resonator looks round and the tuners look like ears. How does it sound ?
