Yes, it would be a huge project.
Not only were there some 1,800 Ortsgruppen by the end of WW2, but also changes in the life of the TN (1919 - 1945), such as in the Landesbezirke/Landesleitungen/Landesgruppen/Bereiche, means that Ortsgruppen numbers also changed over the years and so a proper study would involve a timeline.
But such a list would be a great asset to TN collectors: the ability to identify the location of a uniform from the numerals on the collar patch! That would be neat.
Something of a pipe dream, I fear, but I'll do what I can and naturally share it with this Forum.
