Thanks Ross, I'm enjoying the 16. Let us know what you find on your other Lefever numbers.
Miller, My "E" 10598 has the concave rib, but rather than being smooth it has a light cut pattern all the way to the end. My later "GE" in the 22,6xx range has the flat rib and no bushed firing pins like your "G" 20,633...... For now, we have narrowed the time line of bushed pins and concave ribs between 1889 and 1893. Maybe someone else will post with a flat rib earlier than 1893, and we can further narrow the field in years between flat and concave ribs.
Miller, the other thing I'm curious to know is if your "E" 10,515 has similar stippling on top like my "E" 16 in the image below. Anyone else out there have an early Lefever stippled like this on top?
O-D
