According to this reference, the NUCT "was dissolved in 1970 and the remaining members joined ASTMS."
Could his obit have been in a different union journal? since NUCT didn't exist in 1980?
Elsewhere I found ASTMS = Association of Supervisory, Technical and Managerial Staffs OR Association of Scientific, Technical and Managerial Staffs (I keep seeing both!)
See this page at http://en.wikipedia.org/wiki/Association_of_Scientific,_Tech...
Perhaps the latest union has records???
