Chuck;
The quote you just gave;
My quote: "It typifies the modern cone considered to be longer than many early 20th century guns."
is exactly what I have been talking about.
The dimensions specified in the SAAMI drawings in fact very precisely Typify the early 20th century Short cone, not the modern longer cone. That's all I have ever said. That's the exact point I have tried desperately to make. You yourself said the dimensions I posted taken from an L C Smith drawing could not be correct because the 3°13' angle specified was not compatible with cones of the era, but it was. That angle was specified in 1935 drawings & would produce a cone of approximately 5/8", still not truly a long cone but longer than the 1907 drawings shown & longer than SAAMI spec drawings. It does not appear to me that SAAMI has ever "Modernized" their drawings as regards to cone length or angle, however you want to list it. With either known of course the other is readily found.
It is also noteworthy I think that in older drawings SAAMI shows a minimum chamber length for the
2 3/4" 12ga shell of 2.6136".
This would seem to take in all those "Old" Parkers etc which had 2 5/8" chambers but built to handle the 2 3/4" shell in 12 gauge.
I truly do not see how I could have interpreted what you said when you told me o "Check My Trig" other than how I did. The trig "WAS RIGHT".
The face angle of the Rim seat has been changed by 10° from the Smith drawings to the SAAMI ones, but this was not really discussed, The cone seemed to be the main point of contention & to date you have showed me Nothing Whatsoever I said which has proved to be Wrong.
