The copy from which this electronic file was made is in the collection of the National Air and Space Museum and was located with the generous assistance of Theodore Hamady. The report to which this is an appendix is not available. Typo's, misspellings and the like were left uncorrected. There were however several empty blanks on the test cards which were not included as they provided no information. A portion of
the original which was not legible was also not included.
This test report is for the 2nd prototype N.28 which had no diehedral. This airplane was fitted with one machine gun and two 25L reserve tanks (one on either side of the pilot's seat) in addition to the main fuel tank. The USAS version had diehedral and a second Vickers. The installation of the second vickers required the removal of the 25L reserve tank on the left side of the pilot's seat.
