Thanks Dave!
In the article and graph Austin refers to competition guns. Is there any research on Parker chokes for ordinary (dare I say "ordinary" referring to any Parker"?) Parkers? If would be interesting to measure and plot a sample set or at least 50 Parkers from each decade. This could be done by by distant members using a common reference data sheet such as measure and record each choke at every 1/8" from muzzle to point of no choke/bore diameter.
PS: The 34" 12 gauge DH Damascus in which I measured a parallel section of 1/2" was built on a #3 frame. I would consider it a special purpose, maybe a competition gun.
