Were the characteristics of this alleged gouge in the CE 133* photos measured in any way? If so, the analysis is missing from any of the HSCA documents. Kirk's analysis is nothing but hand waving. There is nothing that actually shows that they are "identical in every respect".
No, Cecil Kirk claimed that CE139 was the rifle in the BY photos -- there was no "determination" done. In contrast, the panel report actually showed measurements and analysis for their claim that the rifle shown in the police station photos matches CE 139.
You're down to trying to argue that Cecil Kirk could not have concluded or determined anything because he didn't use a methodology that you approve of then. That's just a ridiculously silly, and quite possibly megalomaniacal, argument. By the way, human beings have very good pattern recognition abilities. If you see someone you know, even under circumstances in which you don't expect to see them, you recognize them instantly without the need to formally measure any part of them. Don't think that we wouldn't be able to recognize the same gouge in different photographs.
Also, you are incorrect about the use of the photography panel's measurements. They used a series of "identifying marks" --dings, dents, divots, and scratches, labelled "A" through "W"-- for specific identification. Those marks are listed in Table 7 in the report, and they are what that the panel used to determine that the CE139 rifle in the archives is the same rifle shown in the Alyea film, 11/22/63 news photos, and photos of the TSBD rifle taken by the DPD.
Those marks were not measured. The photography panel
did make a set of measurements of the relative locations of certain parts of the rifle along the length of the rifle.
However, those were used to show that a line of argument used by Jack White was based on fallacious reasoning and weren't used to identify a specific rifle.Oh, also by the way, you apparently didn't notice this bit from that portion of the report: "significantly, the largest and most prominent mark, mark S, a gouge mark that appears on the backyard picture, also appears in the gun as it is portrayed in the Alyea movie sequence and in three other postassassination photographs of the rifle as well. See table 7."
