I have a set of 28 pages of TSJC Barrel Shanks dimensions. You can down load these files by doing a search on the internet. Someone posted the link to these on Practical Machinist web site. I have lots of this info when I was a student in 1961 and these latest files are from the 1989 edition. If you need more help let me know.

Also, I have an old copy of the NRA Gunsmithing Guide, Updated, which has tenon/threading drawings for most of the guns available through the time it was published (1983).
