I agree the film was likely Ortho but in the picture you sent us to, I suspect it was also waterbath development necessitated by the high contrast in the subject. The light falling on the chair may even have been specular highlights and he would likely have had to use the greatest amount of contraction available to keep that element printable.
I believe the look you seek is the enveloping light look combined with strong directionality to the light. This is achievable with modern film - and my recommendation is Tmax100.
John Sexton has pioneered a compensated development process using Tmax100 and Tmax RS developer that is absolutely magic. It gives you the ability to render detail in the lightsource when you are in one of those situations where you are forced to include it in the scene. While he uses it primarily on sheet film, he has now adapted it to 120 roll film as well.
If you can find a copy of his book, Listen to the Trees, he used this technique in plates 18, 29, 40 and 49. You have probably seen plate 49 - it is the picture of the charred tree trunk and small needle-bare pine tree still smoldering with strong lenticular lighting detailed in the smoke. It has a very dreamy look to it that is in part, subject matter, and in part - process and printing.
If you are interested, PM me. I have the details on the process and I will be happy to share it.
