As luck would have it, I'm also doing a bit of research on 106 Brigade Royal Field Artillery, as my grandfather served with this unit between October 1914 and April 1919; he was posted to "B" Battery.
I was recently going through the Brigade's war diary at the National Archives, and you may be interested to know that the entry for 31st March 1918 states that Lt. Col. R.G.A. Hamilton was killed while in the vicinity of "B" Battery. To help narrow it down even further, the war diary gives a reasonably precise location: from the afternoon of 29th March "A" & "B" Batteries were covering the Moreuil Crossings, and were located near Estrees-sur-Noye, in or around the woods 2,000 yards west of Moreuil.
I think that after Hamilton had been killed these two batteries were moved to new positions west of the Bois de Senecat.
Hope this gives you the information that you need to narrow it down even further.
