hi
ancestry has all records for ww1 so you need to check there for a medal index card [ mic ] and also look to see if a service record exists as up to 60%were destroyed in a bombing raid in ww2 .
only as you say he joined up prior to ww1 and I take it had continuous service through till the end of ww1 the above is where you,ll find anything on him if by any chance he continued in service passed 1920 then his service record would still be with the m o d .
so firstly check to see what ancestry has .
I,ve looked in the anglo boer war site but can,t see him in there records , but this is a site that is ongoing in adding records of service , and like I said before he doesn,t show up in ww1 pow records on FindMyPast .
