I followed the threads about the camo'd Heyfords with somthing approaching fascination, and FWIW I'm now satisfied that no bomber Heyford ever carried a disruptive camo scheme (until a pic of such a thing turns up, of course). A/C used for training is another thing, and I'd put that under the heading of 'possible - just'.
But, what I want to know is - were any 'Munich-era' codes ever carried on Heyfords? Heyfords apparently stayed in 1st line service with a few units to early 1939, certainly long enough for unit codes to be allocated, but were any actually used on the Heyfords? (A pic would be more than nice!) Certainly other obsolete types, such as the Demon and Harrow, wore unit codes, but what about the Heyford?
