Sorry if this resurrection of the thread is a little late... I've an album of my grandfathers photographs from WW1 which features Peerless trucks quite heavily. He was a driver with 346 MT Coy ASC in Salonika, Northern Greece. This little sideshow ( Only 6 UK divisions involved !! ) was in support of "Poor Little Serbia", invaded by the Bulgarians....
I have more if they are of interest ? ...several featuring vehicles in ditches, so that may not have been the only bottle of White Horse involved... :-)
