If I remember correctly Jordan I think the original $CRB had a name change to the $CCI ( continuous commodity index) as you say back in around 2005.

Which still exists as an etf called GCC ( Wisdom Continuous Commodity Index)

The New $CRB was an entirely new index with different weighting from the original $CRB…

I think The Original does live on as GCC however.

This is from memory .

So perhaps need to have a look at the GCC

GCC ( It’s a start I guess)
