A friend of mine 'moved up' from 4x5 to 8x10 and gave me a new box of 4x5 320TXP that he does not need anymore.
I normally do my own speed and development testing. However, last year when I tested FP4+ in PMK, I found that my results were were a very close match to Hutchings' recommendations in 'The Book of Pyro'. Because of this, I thought I could refer to 'The Book of Pyro' and use Hutchings' recommended values for Tri-X as a starting point. Much to my surprise, the book only gives times for 'Kodak Tri-X' but does not state which particular emulsion the values are for..
To cut to the chase, I have not only scoured this forum, but many others, plus UseNet, and have not found any recommended values for 4x5 320TXP (or TXT as it was known until recently) in PMK.
Would anyone care to contribute their times and EI for either 320TXP or Tri-X TXT? I sure would appreciate it.
