Barrel dimensions for the old classics?

[rifletuner]

Is there a good resource for the barrel contours used on the old Rigby, Westley Richards, Jeffery, Holland & Holland, etc bolt action rifles? I would like to see what profiles were used, and what they looked like in photos, but cant find much online. I did a search on the forum, but didnt turn up anything, but maybe I just wasnt searching for the right thing.

Obviously the specific dimensions will vary a bit from the smaller bores to the bigger stopping rifles, but it would be interesting to see what the different makers used back in the day.
