Parts dump
 

Here is an undated photo of a Canadian parts dump. The boxes (in the original hi-res print) are clearly marked "Austin Engine LV7/AN" The last bit "LV7/AN" identifies the supplier as Austin. The sign in the foreground uses the LV7/FW code for AEC. The AoS of the sign identifies the Canadian unit as the 56th Light Aid Detachment (type C). I wouldn't have expected a LAD to operate a parts depot of this size and perhaps Mark can fill us in on this.
