ok sorry fellas . i meant to get back here and show you all what i was getting at .
a fella named Patrick Hallman did a study of this subject many years back , with the help of Chuck Dixon.
Sadly Patrick is no longer with us .
But he put his findings down in a book called ;Seeing through the eyes of Yesterday ., The Kentucky Rifle and the Golden Mean .
Im not sure if the book is still in print or not . But for thos inspiring to do their own layouts , its IMO a very valuable thesis .
He shows how many rifles were laid out using the Golden mean . and the 3 to 5 rule of proportioning .
Everything from the lock mortises , wrists , patch box, lengths of pull , trigger placements. Even finials and such .
Here is a scan from Patrick’s writing showing the layout and how the Mean was use by John Armstrong
Now when I built Magpies little NW trade gun , I followed the rules of the Mean so as to properly proportion the rifle to him . The only exception was that I enlarged the length of pull so as if he did grow alittle more . The rifle would still fit him .
This video is of the Christmas party where Magpie was given the rifle .
At the time , he was 12 . As you can see , because of his illness . He is no bigger then his 5 year old brother sitting on the floor next to him .. But by Using the mean . the rifle is proportioned correctly to his size .
Sorry the video may be very large for those on dial up to download
i will say that even today , no rifle has ever brought me more joy to build then Johns little smoothbore
