That's interesting. The Dead Sea Scrolls date to between 170BC and 70AD. They include the Apocrypha in the LXX translation. Or are you "spinning" (in the correct definition of course) looking only for a complete LXX?
Are you willing to accept everything found in the Dead Sea Scrolls as the basis of your Scripture. Are you willing to accept the Pseudepigrapha contained therein as Scripture?
It appears you are claiming there is such a thing as a Septuagint. There isn't. Why don't you just tell me how old the earliest available version, or portion of one, is.
