Hm. I’m not sure what you mean. Nikon 35mm film lenses aren’t described in T-stops since they aren’t motion picture lenses. They use f-stops. And the Nikkor 8mm f/2.8 lens couldn’t have been used for anything in 2001 since that model was introduced in 1970, after the film came out.
The century rehouse is listed in Tstops, though I think it's actually a T3.1 when measured
