[DX] Help KG4NP

[F6EXV]

Hi all
Not sure if this is a good place to ask, but I'll try....
I  worked KG4NP on October 24th, year .... 1987 (almost 20 years ago)
I cannot trace any info about that station on either qrz.com, or 
searching through google. So I suspect this guy made very few QSO.
Mine was on 80m SSB.
I have never got a card for that contact, and need it for the DXCC 
Challenge (each point is now hard to get)
Anyone would have any hint of any kind ?
Who was the op ? Is this op still around with what callsign ? Any email 
address ? Anyone got a card ?.....
Many thanks in advance
