There a bunch of Word and Witness but they are listed as Church of God in Christ - white, so I am not sure they were a Oneness publication?
If you go here
http://pentecostalarchives.org/searc...ullTextResults you will see three boxes, labelled "Country", "Denomination/Organization", and "Publication". In the country box click "USA", in the Publication box click the name of the publication ("Word and Witness"). Then, under the Country box click the button "Set Limit" (click that AFTER you have selected USA and WORD and WITNESS). Then, in the bottom left click "Search" and it will pull up all the Word and Witness issues they have available.
