Well People, the "old man"", has basically "fanned out" Have yet to find any tailoring patterns for Military Taryan trews, ( either modern era or earlier.)
Even the MoDs for sale on the web are drying up. ( but some are still out there, you just have to search & be patient.
As to having new ones made, there are some "tailors" on the net that say they make them.
Just a word of "CAUTION", many, who make the claim, are not "really" ( Be sure that they have the Military waist, that leg seam is on INSIDE ( Not Outside ) & they are 16oz +)
Here is one that looks Good ( actually would be period ) -
