Thanks brother Drew. It is from 1914.
If I'm not mistaken, I thought someone brought up the subject of a 5 pin lock. There was nothing special about it, just another 2 pins (screw posts) for the bridle. I also believe that this was in 1907 only. (but never say never).

Dr. Brown, in going over the previos posts, just now, you gave it away on the first page when you gave the dimensions of the barrel lug.
This is what happens when one does not pay attention. (me)
