RCAMC stretcher jeep markings (need help!)

[derk derin]

Hi Clive,
Thanks for the starting point for my search.So far I have found out that the RCAMC field ambulances serving with the 3rd Can.Inf. Div were;

7th Canadian infantry brigade
75(black background) 14 field ambulance RCAMC (Moncton,N.B.)
8th Canadian infantry brigade
76(black background) 22 field ambulance RCAMC (Halifax,N.S.)
9th Canadian infantry brigade
77(black background) 23 field ambulance RCAMC (Petawawa,Ont.)
In searching invasion maps for the 3rd Division I noticed that the 7th Canadian infantry brigade were heading in the direction of Vaucelles.Can I assume from this that it would be a stretcher jeep of the 75 field ambulance or is there a more conclusive search I can try to find out the unit?
The formation sign will be french grey with a yellow leaf?
I would also like to find the type of stencilling font for the W.D. numbers on the hood CM4233488.Would these be 3 inch numbers?Any idea where I could find them?An internet search found a few close matches but nothing like the jeep has.
Thanks,Derk.
