I am sorry, but I am a little dense this morning, but I am having difficulty understanding your question.
Having consulted the two editions of the KIT I can't see any difference in the number of citations. Both editions use the Tetragrammaton 237 times in the main body of the text, with an additional 72 times as a footnote, making a total of 309 occasions where it is used.
The only difference is the number of authorities [the J sources] that have been consulted. The ' 69 edition consulted 21 of these sources, while the ' 85 edition used 27. It would of course make no difference if the WTS quoted an additional 100 other sources, unless it was proved that the original writings did so.
It seems hollow to think that after 34 years of intensive searching for additional documents, the WTS could only find an additional 6. Of these: two were released after the original edition of the NW Translation in 1950. [J 22 in 1979, 23 in 1975] another one, J25, is in fact a 20th cent publication, and is not even a translation. One, J24, was published in 1863, one in the 18th cent J27 [1796] and the sixth, the oldest was released in the 16th cent. [J26 in 1533]
There are other anomalies in citing these sources:
1 In the ' 85 edition of KIT, the WTS does not reveal that J 2 and J 3 are essentially the same work, only that J 2 was revised into J 3
2 In the original edition the source known as J 10 "Gospels in Hebrew" published in 1800 in London, has been changed to read: "The New Testament ...... in Hebrew and English" published 1789-1805.
3 In the original edition, J 19 is described as : "John in Hebrew" Published by the "Jews Society of Haifa, Palestine, in 1930, arranged by T C Horton". The revised edition of KIT, however, tells us that this is in fact "John, Heb, by Moshe I Ben Maeir of Denver Colorado, and published in 1957 For some unfathomable reason, the original ' 69 edition listed "John" in italic print. It is replaced by normal print in the ' 85 edition.
For a fuller treatment of this subject, you can consult the book "Witnessing the Name" written by WTS researcher, Doug Mason. It is available from Freeminds.org
There is also currently a thread running on JWD making the original 69 edition of KIT available to researchers.
