Try a "Name or Place" search at:

http://www.qrz.com/i/names.html

Enter the name of the town where he was most active. This will give you a
list of hams currently active from that town. Search through those names for
some old timers (the date of birth is listed on most entries). Try writing
or emailing a few of those old timers to see if they remember him and his
call sign.
