Hello Mike and Tony,
Thanks for the clarification.
Mike the last time I checked the 2/1st Pioneers' did not have the "war diaries" online - unlike other battalions that are available through the AWM site. Are they getting around to putting it online; or do you think that since is has not happened by now that it won't be happening?
What TAC plates and features would have appeared on the 2/1st Pioneers trucks in 1940?
I found this link which shows the triangle
