Work shirts doesn't seem to have changed much. You can find the measurements here: http://www.endclothing.co.uk/brands/engineered-garments/engineered-garments-work-shirt-75954.html
What is worth noting though is that they seem to have increased the size of the Round collar shirt. A small now has the same pit to pit width as a medium work shirt. And last FW12 I had to size up to medium in both round collar shirt and 19th cent. bd shirt while I still went for small in the work shirts.
