I Am Looking For A Very Specific Dataset Used In The Paper Short-Term Variations And Long-Term Dynamics In Commodity Prices (2000)

I am trying to replicate the model in this paper and to make sure it works I would like to apply it to the same data as in the original paper

There are two datasets used, one is the weekly prices of 5 NYMEX crude oil futures contracts from 1/2/1990 to 2/17/1995. The paper says that these were made public by Knight-Ridder Financial, a company that has ceased to exist since.

The other one is a set of crude oil prices by Enron Capitial, a company that has also ceased to exist since.

I doubt I could obtain the second dataset but I was wondering if anyone had any suggestions on where I could find the first dataset by Knight-Ridder Financial. I have tried accessing their website through internet archive but I wasn’t able to find anything on there, nor was I able to locate the original publication.

Bloomberg is not an option for me right now either.
