I'd have to go to his house to find the first edition as we don't have one here in the office but all three of the other editions we do have all say Westover or Lewiston and bath is omitted after whirlpool. I realize that doesn't explain why, but it does show the changes have been there through several printings.
Hey, Ms Mod! Don't trouble youself - I will go over to his house for you. He probably keeps the editions in the kitchen!
