That jacket is from 2005. Fabrics and construction have improved considerably. The down not so much. Pretty hard to make any direct comparison to a current Fitzroy. Depending on how that jacket was stored, cared for, and what you need it for it might be a great jacket.
Mikey nailed it. That jacket was simply called the "Patagonia down parka" and it was 850 fill. I had one, it was very warm. As long as the shell material is good it'll be a great jacket. I would check the stitching for degradation and see if there is any UV fading on the shell. I think an XL weighed about 2 lbs but the fill ratio was very high. I had one that I planned to use in Alaska but that trip never materialized.
