The survey simply takes all the characteristics down. When I sort, I can sort by anything.
You want to see all the guns with /26\ marks, no problem.
You want to see every 16 1/2" gun, check!
You want every gun with a III on the sight ladder, a pinned barrel, and a late two sided firing pin, yes sir!
It's the patterns that are going to make the connections between the various arsenals.
As far as categorizing them, since we don't have a known refurb mark on Chinese guns like the Russians do, we have to take things in the survey with a grain of salt. A single instance of a certain feature on a certain series of rifles needs to be repeatable, otherwise it could be a refurb replacement part, an error in someone entering info in the survey, or even someone dicking around and trying to throw the survey off. We simply need more data, and that takes time to come in.
