I came across the following Book which mentions a Bible, "The Translators' New Testament," published by the British and Foreign Bible Society (Bible Society) in 1973. There was a second unpublished, but circulated volume called, "Old Testament Translator's Translation (OTTT)". From what the online book explains these would be great resources, but there seems to have been some intellectual infighting and that killed the OTTT and TTNT was removed from publication. The Bible House appears to have been involved towards the end of the OTTT project and was overseeing it at the time it was shut down.
The purpose of these testaments was to give a native speaker (eg. Cree) with a working knowledge of English the ability to refine previous Bible translations into their native language without years of studying Greek and Hebrew. This was done by providing explanatory notes for each verse.
It seems that someone in our community would know of these works and be able to provide some insight or be able to check into the availability of these works.
