I of course haven't seen the actual books. The info I gave was a semi-quote from the Parker Story. I don't have Volume II with me, but the note I took says it is on page 517 of Volume II. It is a reasonably complete discussion and quotes some typical bore sizes etc. This subject is tied to other discussions of brass shell dimensions. This discussion runs at least through page 523 and includes actual measurements of bores from some early guns that are stated to be totally original.
The chart on page 519 lists bores as typical modern sizes, and these are quoted by a lot of people as standard for Parkers. This is only strictly true after 1920 I believe. Up through around 1880 it probably wasn't true, and may or may not have been from the 1800's to sometime closer to 1920.
There also appears in that book a picture of a tag distributed with guns of that vintage which gave Parkers optimum load for the 10 gauge and they recommended loading the shells with 9ga over powder and overshot wads.
I have also been told in a response about stampings that one of the marks with no known meaning is an "O" found on some 12 gauges. If the Parker Story info is accurate, that could well explain that mark. If some members have O marked 12 gauge barrels, it would be interesting to see their bore measurements.
One thing I have never seen is any similar discussion about the 16 gauge. I have one from 1901, but it is a standard 16 ga bore size. If any lifter model 16 owners have measured their bores, it would be interesting to know if any are overbored.
