I am of the opinion that Bradbury, Newbery, GM, GN, Kookaburra, Puma, Adidas etc. fall into the same category - with some of their bats (mostly for their sponsored players) being handmade but the majority of them would be machine made and hand finished. The lower grade bats would be contracted out to companies in India. I would be surprised if the 4000 - 5000 top end bats that these companies sell globally would be hand made. Assuming it takes 2-3 hours to make a bat, it would mean a bat maker like Tim or Paul would spend 8000-15000 hours making bats each year, which is not possible as there are only 8,760 hours in a year.
This is not the case (i assume so) with M&H, Salix, Warsop, Blueroom and other smaller businesses who do not sell as many bats as the above mentioned big names.
Judging by the quality of the grips put on all the Bradbury bats that are available off-the-shelf, I feel they are made in India.
