This apparently, is one 'Alf Martin' in 1908:

I am afraid my knowledge of uniforms from this era is pretty poor, so I am wondering if anyone can please tell me if Alf is with The Royal Artillery, or HAC?

The image os his cap badge is just not good enough for me to see clearly, so hopefully his uniform will pin his unit down.

With thanks,

Peter
