The CIP standard ctg drawing were available online as well. Last time I visited the site it was messed up and now I dont even have the link on this computer. If someone has a link to the unbroken site, I'd like to see that and add to my favorites. Those would be official numbers and I believe(?) both English and metric, which is convenient for making comparisons. I forget ...maybe not both.

Here is the site (but I dont see how to get the drawing PDF files):

Here is a teaser (how to get more?, Table I and II are for rifle ctgs):
