I started a thread on this many years ago but did not have the documentation ready. I recently unearthed the documentation and have put it into a PDF.
Back about 15 years ago my best friend worked for a Christian Book Store. He used to order foreign Bibles for the store and one evening I was thumbing through a Thai Bible on the shelf and was dumbstruck. The endsheets and some of the maps where identical to the NWT except they were in Thai. But, it wasn't the NWT in Thai. It was published by Thailand Bible Society. We decided to contact the Thailand Bible Society and got a reply admitting that yes, the Bibles had been printed for them by the Watchtower Society. It was not the NWT but some version the JWs liked because it uses "Jehovah" in the Old Testament. This version is known as Thai Bible OV83.
I've made a PDF of the correspondence between my friend and the Thailand Bible Society. The initial queries were not too pointed because we were not sure if we were dealing with a JW organization. It turned out that this was a regular Bible Society of Christendom. The official from the Thailand Bible Society said the Watchtower received permission in 1992 to publish the Thai Bible OV83. There were 2 different editions printed by the Watchtower Society. The first print run was for JW use. But, what we had found was one of the copies from the second print run which was a custom edition the WT Society did for the Thailand Bible Society. This custom edition removed "Watchtower" from the publisher's page (the page after the title page) and only listed the Thailand Bible Society. In other words, the Society did a special custom print job for one of the Bible Societies of Christendom!
Page 5 of the PDF file shows that the Watchtower edition's publishers page compared with the publisher's page of the Thailand Bible Society. The WT edition had 4,500 copies and clearly mentions it was printed by the Watchtower. The 2,000 copies printed by the Watchtower for the Thailand Bible Society omitted the Watchtower imprint and only lists the Thailand Bible Society as the publisher. The Watchtower Society did a custom imprint for the Thailand Bible Society! Page 17 of the PDF file contains a statement by the Thailand Bible Society that they ordered 2,000 copies of the Thai Bible OV83 from the Watchtower Society "following the normal procedures of buying and selling."
Let me be clear. There was nothing illegal or unethical involved here. Custom imprinting is done all the time in the publishing business. My guess is that the Watchtower Society contacted the Thailand Bible Society for permission to print the Thai Bible OV83 and the Thailand Bible Society asked if they could get some copies for themselves to use also. On one level, I want to say "Bravo!" to the Watchtower Society for working with another religious organization. That would be a step forward for them. However, the Watchtower Society has not renounced its separtist stance regarding other religions. What is clear is that the Watchtower Society violated its own principles in doing a custom print job for a Bible Society of what they think is Babylon the Great. The brothers at Brooklyn Bethel produced 2,000 Bibles as a print job for the Thailand Bible Society. Mind you, these Bibles were a special print run that removed the word "Watchtower" from them and only contained the name of the Thailand Bible Society as the publisher.
Can you imagine what would happen if a JW were to do a job for a church? Say, a JW roofer contractor taking a contract for re-roofing a church? Or, a JW working in a factory which specialized in making religious items? Or, a JW working in a Christian bookstore? That would not be allowed and they'd face disfellowshipping and shunning. But, here the Watchtower Society does custom printing for another religious organization!
The PDF (about 2.5 MB) of the correspondence with the Thailand Bible Society can be downloaded from this filesharing site:
The file contains copies of pages from both the Watchtower version of the Thai Bible OV83 and the Thailand Bible version as well as a picture of the Bible itself.
