PS, looking at the lock, the outer edge of the half cock notch does stick out a little more than the outer edge of the full cock notch.
OK, I was curious to see on Five New Old Stock (NOS) EuroArms Tumblers what was the distance from the Arbor Shaft to the Full Cock Notch compared to the distance from the Arbor Shat to the Half Cock Point. It appears they were manufactured so the Half Cock Point was further than the edge of the Full Cock Notch as shown below. Not only that, but the outer rounded edge of the Half Cock Notch was further out than the Half Cock Point.
1. Arbor to Full Cock Notch: .100 “
Arbor to Half Cock Notch Point distance: .128 “
2. Arbor to Full Cock Notch: .105 ”
Arbor to Half Cock Notch Point distance: .117 ”
3. Arbor to Full Cock Notch: .120 ”
Arbor to Half Cock Notch Point distance: .130 ”
4. Arbor to Full Cock Notch: .112 ”
Arbor to Half Cock Notch distance: .130 ”
5. Arbor to Full Cock Notch: .125 “
Arbor to Half Cock Notch Point distance: .132 “
One thing I commonly did on “Enfield Type” Tumblers of all sorts, as I was shortening the Half Cock Notch, was round that sharp point EVERY time I shortened the Half Cock Notch. This helped keep the Sear Face from catching on the sharp point of the Half Cock Notch.
