From looking at more about James Bond films, I found what is supposed to be a better version of the 1950's James Bond film:
Amazon.com: James Bond Casino Royale (1954): Barry Nelson, Peter Lorre, Linda Christian: Movies & TV
Obviously, at that price, it is for people who really, really want to be complete. It is B&W, made for TV, and not overly long, so you are paying a lot for it. This would replace the DVD in the original post above, for the extra on that disc (though you would need something else for the 1960's spoof, such as the BD of the first post above).
Please note, I do not own this, nor have I watched it. I am judging from reviews on Amazon, and consequently cannot be certain that this is the best one to get. And, again, this is only for completists or those very interested in 1950's TV, not for the casual fan.
