Rich,
Not that I know of. Not in the Concord series, anyway. Maybe in Osprey? Not sure. Sadly, though his Tank Battles of the Pacific War has many great photos, many of the Shermans, by his own admission, are miscaptioned as M4A2, when they should be A3. People keep buying the book, though, and the myth is perpetuated. Kind of like the Earth Brown over OD camo on Shermans in Europe, which he now says were more likely black over OD.
A better source for Pacific Sherman info is Oscar Ed Gilbert's Marine Tank Battles of the Pacific War. It's not an Osprey or Concord book, but is the best source on the topic. He's pretty much a regular over on ML as well.
HTH.
