I have this postcard dated 1907 to L/Cpl J. [ jim ] Bundley North Staff Rgt. H Coy 1st Vol Batt. Morfa Camp. North Wales. The camp was used in ww1 and ww2. Link to camp info. Site of army camp, Morfa Conwy - History Points Keith
It’s 1st Vol(unteer) Battalion rather than Vad. Would have been their final annual camp as Volunteer Units would have been phased out with the introduction of Territorial Force in 1908. You may find TF service records on findmypast if he continued to serve. Steve
