It appears the top drawing on pg. 162 and top drawing on page 163 are identical with exception of print dates. They both us decimal inch measurements.
The set on the bottom of page 162 uses fractional measurements and when converted to decimal all the dimension are not the same as the other two drawings and obviously the date is different and fall between the earliest and latest dates.
Why the 3 prints and how different, if any are these kickers between gauges and frame model (R vs FW)
What are the consideration when fitting these to a gun.
Many thanks
Travis
