Cruden’s Complete Concordance was first published in 1737 by Alexander Cruden. It is a concordance of the King James Version. This PDF is a scan of the 10th edition and is 886 pages. It also has a pretty cool “Memior of Mr. Alexander Cruden” on PDF page 16. The actual concordance begins on page 23.
The scan is pretty clear and Ctrl+F for searching works relatively well.
