As an aside, and totally off topic, but because the pics are posted here in this thread, take note of the difference in the quality of the internal parts of the Traditions lock and the two Kibler locks.
 
Wiscoaster's post of the Traditions lock in #6 & #12 shows they did not put the pivot point of the fly equal distant between the notches like a bell clapper. The fly pivot is set too far back making it a mile too long at the half **** notch. The sear has to work too hard to drop down around the fly to clear the half **** notch. I guess the designer was looking at the Tower of Pisa for that basic law of physics rule.

😄 You're probably right, yet it works. I don't remember if I mentioned the Trapper has a double-set trigger. I don't know if that makes any difference wrt the geometry of the the tumbler, the sear and the fly. Still in the learning stage wrt to flintlock lock works, I guess. ;)
 
When I was young I either sketched or focused very carefully on anything I was about to disassemble. Good for all of you who take “before” photos. I do that these days as well since digital photography is so easy and you don’t have to wait for a roll of film to be developed. They have saved my butt several times, especially on something I didn’t reassemble as soon as I had intended.
 
Never in my life have I seen the fly installed on the lock plate side of the tumbler. All locks I‘ve ever seen has the fly on the bridle side of the tumbler, and I’ve seen many locks. Now I’m curious, who made that lock?
I have 2 Dixie Gun Works locks with the fly on the plate side. Pretty sure that I have another one but not sure which one it is. I am not going to start taking locks out to see which one it is. With my luck it would be the last one I check. I guess I could check the last one first. Naa if I have 2 choices I will pick the wrong one every time.
 
Great write up. Mostly super helpful cept from a couple wise-n-hymers.

Thing to keep in mind is the rounded edge of the fly is always facing the sear so as to prevent the sear from slipping into the half **** notch when the set trigger is used. Reason for this is in the speed of the mainspring when the set trigger is used. Using the front trigger with yore finger is a bunch slower and the sear is yarded back hard enough and long enough to prevent that sear from slipping into the half **** notch. MOSTLY!!! Some single trigger systems also use the fly 🪰 to help this also.

This is worth exactly what you paid for.
