Interesting picture of the reserve 17th Battalion. Looking at this picture it has some similarities of pictures taken of the 14th Battalion (1st B'ham Pals) that were taken in Sutton Park.

This postcard is interesting for a couple of reasons. There are four soldiers at the very front and four name on the rear of the card.
Lt Col Bowhill (Commanding officer) Major Hocks (I think) 2nd in charge, Capt Riley officer commanding B Company and 2lt Ayre as Adjutant.
Also looking in the back ground I think that may be the Crystal Palace once the head quarters of the 1st B'ham Pals who had moved on when this picture would have been taken. Perhaps Terry could confirm or put me right. I believe the Crystal palace was burnt down some years later.
I think the 17 Reserve can often be over looked as they didn't go out to France with the original Pals as such but were used to replace soldiers lost by the other three battalions, but make no mistake many of the reserve soldiers were killed in future battles, being replacements didn't keep them much safer for long
