Still looks wrong to me....
That type of metal plating came in on 9 speed.
Unless it is a 9 speed cassette respaced to 8-speed.
Correct cassette for 8-speed Ultegra was HG70/1 and HG90/1 which weren't drilled out. Dura-ace 8.speed cassette had matt surface and wasn't drilled out either.
If top 3 sprockets have spider, they are 9-speed.
