May I just pick-up the reference to wool for uniforms? The Ministry of Supply acquired the whole Australian wool clip in 1939, thus frustrating as a coincidence, German plans to exchange wool for Opel cars and possibly trucks. I assume that as the war dragged on the availability of spare wool not required for the AEF etc. and shipping problems meant that the supply sagged?
Excuse pun!
Reference to coffee table books reminds that I co-authored one: it was designed to be landscape format so as to sit nicely on tables! Regrettably only a handful of Canadian vehicle photos though. Of course, the discovery of 220 professional photos in a tin box that had survived unscathed was a miracle. It did however provide irrefutable evidence where relevant!
