I believe that the M770 was the first aluminum axle version. I have M756 and M760 on my touring bikes. I have never seen 130mm XT hubs, although SteveD (above) said they existed.
When I built up another touring bike this past spring, I noticed that Surly was using the M770 hubs on their LHT but according to their catalog on their Big Dummy (a heavy duty cargo bike) they used an older steel axle M756 XT hub. For that reason, I used a steel axle hub on the touring bike that I was building, as I wanted cargo bike capabilities for my touring bike. (Surly has changed parts again, they now use a Deore on the latest version of the Big Dummy.)
When you buy spokes, measure the hub because they made subtle changes over the years and if you use the dimensions off of the internet, they might be from a different version of the hub.
