Amatuer Call Sign Historical Research + Silent Key

[fineshot1]

This has been a dead end for me after trying google all day. I am attempting to research
a ham i used to know back in the late 80's but he must be a silent key now or perhaps its
been so long i can not remember his last name properly. All I get is the ham that now has
this call sign which does me no good. If anyone knows of a sure fire way to research this
I would appreciate knowing and I am sure others on this site would like to know also.

just about every thing under the sun and I could not click on the blocked link.
