The king james bible that you will find if you buy one generally in a store is the [1769 KJV].
Below is the bible that I recommend. You can buy from cambridge or from your national internet bookstore.
There is supposedly one error in the AV1769 as compared to the Oxford 1833 reprint and the AV1611 and that is the he instead of she in the Song of Solomon 2:7. But once you know about it, you can read the AV1769 without misinterpreting it. Also capitalization might differ.
