I've got a set of the original XT V's (BR-M739), which date from 96-98ish. Currently on my commuter bike but soon to be surplus (I've offered the levers to someone else, without which there isn't much point keeping the brakes... )
I think they're in good condition, except for some surface rust on the little black links between the pivots and the pad holders. This would probably clean up ok though.
Can get some pics this evening if you're interested.
