As a point of interest, I have one of General Crerar's staff car flags as shown in the photo from earlier in this posting - it denotes the General Officer Commanding, First Canadian Army.
Mine may well be the one in the photo as it was given to me by Finlay Morrison, his ADC. The "Crerar Trailer" at the Canadian War Museum was Finlay's office.
He had a fancier flag with tassels and gold maple leaf (instead of yellow) for his staff cars. Post-war he used a different design flag in Canada with a different appointment.
In my collection I have almost all of the WWII Canadian staff car flags and some from from post-war.
Some (most?) division commanders customised their swallow-tails because officially were all the same (red with gold/yellow maple leaf). The British Div Comdrs did the same. I'm still looking for these customized staff car flags.
