New Post: What's the difference between two legacy gbid's?

For many legendary items there are two legacy versions in the gbid list. What's the difference?

Also for some items there is an 'old legendary' gbid, which I assume is the 'loot 1.0' version of the item, but I thought these are exclusively on PC as the console version was born with loot 2.0. Am I wrong?

Thanks.
