Sorry Raimey:

Hope this helps. There are other books by Mr. Garwood, but these are the ones I have on loan at the moment. Pertinent articles in them include:
-"Fallacy of choke"
-"Choke versus cylinder-permissible aiming errors"
-"Choke-a neglected aspect"
-"How choke works"
-"Mysteries of choke (I)"
-"Mysteries of choke (II)"
-"What is my choke?"
And several others on ballistics, patterns, range; all very enlightening (to me at least).
I should mention that I finally measured (and patterned) my son's model 53 16bore AyA and the Galazan choke gauge I used would not go in in either of the barrels. As far as the shooting we usually do, it is really a handicap to have such a gun that was surely made for live pigeons. It needs opening up asap, and I would choose .004 & .017 (using the "Choke & Chamber Music" chart as reference)
