I have an almost new pompier's hook for your collection of climbing tools. Gary has one that's similar, but this is larger It has a built in circular ring attached to the smaller portion of the hook and can't be taken off of the larger pompier's hook. It has the twist lock for safety, that you can open to attach to a ladder rung, etc. It weighs 2 lbs. 6 oz. (1.179 340 162 kg.) If you're serious about wanting it, make me an offer that I can't turn down. Pictures are available.
