1919 1st Battery, Canadian Field Artillery     

No, not a Namaimo team as earlier suggested.  Thanks to the incredible work of Andrew Taylor, our UK colleague, this is a photo with a Nanaimo player - Phil Piper (middle row, far right) - in it, but is the " ... Reserve Artrillery Brigade" - the location is Camp Witley, Surrey, UK,

Andrew first thought this was likely 1917, but by chance I noticed the player in the middle row, left, as being very familiar.  Rich Necker then chased that down to Camille "Lefty" Delcourt and from Delcourt's military record Rich and Andrew managed to pinpoint this as more probably May-June, 1919.
