If you go to this site;
http://www.1stapostolic.org/old_publications.htm you will find the Pentecostal Outlook all the way back to 1938 to 1945, then it became the Pentecostal Herald and they are on there from 1946 to 1956. There is also some Illinois, Indiana, Kentucky, Louisiana and Ohio periodicals on there that are old also. They are very exciting to read and I have used some of the articles in our church bulletins from time to time. Hope you find something on your dad Neckstadt. Bro. Sam might find something he likes also !!
