Plus the Manchester Stirling and Halifax which were due to replace the 7 you mention and flew in the mentioned period, that is 10 in total, how many is "much" if 10 is "not much"The Brits don't have much in this category (bomb bay with bombardier). Only Albemarle, Beaufort, Blenheim, Hampdens, Mosquito, Wellington and Whitley were produced in any number. Of these the Mosquito is the best. Though I do like and also want to include the Bombay and Harrow transport-bombers for their robust fixed undercarriage. If they could be spared I'd have sent all of both to North Africa, India-Burma or Malaya.
