Jim,
One of the ratchets in your cluster is a sleeper; it's the Williams roundhead. Arguably one of the best ratchet designs ever built. Do yourself a favor and start using the Williams ratchet. Unless it broken or gummed up, I think you will be surprised how nice this ratchet is. Very smooth, fine toothed, good balance, nice knurled handle, and a tad longer than most standard ratchets. They are a joy to use. In short, it's a keeper...
At any rate, that is a fine grouping of ratchets you picked up. Congrat's!!!
