Chris referred to this message thread in his separate 17 April 2017 thread about his gran getting strafed by a Luftwaffe invader.

I just happen to have scanned pg 124 of the Oughton book yesterday! — only at low resolution and too dark (setup to optimize the use of Optical Character Recognition software on the text), so I have a not-very-good image of BZ717, the Liberator which crashed near Chris’ gran’s home.

If I get around to scanning this photo properly, I’ll post the result.
