I have two Parkers in the 1905-7 range. Both were bored .040 within a thousandths of an inch on their left barrels.
I'm suspicious that makers tested and developed chokes for pattern density, then replicated the dimensions for production of guns. It would be interesting to have a survey, comparing a maker's diameter variation for a given choke. The problem with a survey of that sort, of course, is that these guns are the better part of a century old and could very well have been polished out, honed, reamed, etc., so the data would be of little value.
From my little knothole, if someone told me they have a Parker, LC, Fox, etc that had a full choke marked gun that had a measurement that was something outside of what I would expect, I'd be looking for indications that it had been modified.
Regardless of all the banter about pattern density, choke in thousandths of an inch is the only information useful to me when assessing purchasing a used gun. This is because: 1) I wouldn't know what load was used if pattern density was given instead of dimensional choke measurment, 2) it's unlikely I would use only that load or use it at all (we all have our pet loads), 3) the components for that load are probably no longer available if the load was from yesteryear. 4)I'm not so concerned about pellet count as to select say one gun over another, when going into the field to hunt, but rather more along the lines of this gun has tight chokes, this gun has medium chokes, this gun has open chokes, this gun makes me feel good to hunt with, etc., 5) I have a general expectation of performance based on choke dimension that has proven very reliable to me (nobody selling a gun could convince me that their 12g gun with a .025 choke would perform as I would expect a full choke gun to perform on a variety of loads without demonstrating it.
Frankly, I think the industry for production guns has long ago moved to a dimensionally based choke approach. Besides, pattern count is just one way of quantifying tight, tighter, looser. You left out the part about knowing if the gun had been fooked with by a moron. have a day Dr.WtS

Chuck I be the first to start your survey with five shotguns. There is a mixture of imported vs American.
ERA 12 guage--Made in Brazil. My "to go gun" and "loaner".
Left barrel .706 Right barrel .717
Model 24 Winchester 12 guage "The Club"
Left barrel .700 Right barrel .720
Remington Model 1900 12 guage damascus
Left barrel .706 Right barrel .703
Pellet count 35 left barrel 30 right barrel
F.S. Francisco Sarriugarte 12 guage Made in Spain
Left barrel .690 Right barrel .707
Remington Model 1889 10 guage damascus
Left barrel .746 Right barrel .760
Pellet count 56 left barrel 50 right barrel
What struck me odd was the 1900 Remington's bore size vs. pellet count stamped beneath the barrels as per Remington's testing. It patterns very close to Remingtons pellet count.
Non of these guns barrels have been altered.
