While going through some 1903 peep/slides I notied that the early ones had the white line and were unmarked, than I found #5 peep, than #5 lined-out and remarked 6.

I found one peep marked #8. I used a 5/64 inch drill which went throuh the peep (the 5/64 inch is .078 inch).

My question, was there a number 8 used by the Army ? or was it made-up by some company ?
