VH 16ga Bore Diameter
 

I have 2 VH 16ga Parkers. One is a 1901 model with a .665 bore diameter. The other is a early 1930
Model with a .675 bore diameter. Wall thickness is over .20 in both guns.
I was a little surprised when I read the .675 diameter in the later. Is that unusual for a Parker or should I be skeptical & investigate further? Chokes are basically IC/Mod in both guns.
Thank you in advance.
