Processing Kodak Tri-X Ortho 4163 in Rodinal?

Hi,
I just bought some expired Tri-X Ortho, and am struggling a little with the limited processing data available. the datasheet only lists HC110, DK50, D76 and Microdol-X, and my dev of choice is Rodinal. I have tried cross referencing other datasheets for Tri-x 320, but they are not even close to these times, so I am finding it hard to even guess what dev time I should use.

Have any of you got any suggestions?

I plan to expose around +2/3 stop, then dev at N, assuming that will compensate for age.

Thanks,
t

Try 2x the exposure, or 4x.

Also strongly suggest HC-110, dil B, 7'.
