There ought in theory to be a set of service records covering his 6 years service, which could have started any time after the age of 17, though more likely to be at the time he was resident in Beaumaris.
The original service records for the Militia before 1908 are usually in category WO96 at the National Archives, Kew. The company Findmypast has copied and made these available online since last year (on a payment/subscription basis). I had a look at the free index, but an Albert / Albert Edward Jones born 1878 (+/- 5 yrs) in Flintshire or Denbighshire threw up few if any likely candidates.
If he went over into the Special Reserve after 1908 the records should be with the rest of the Army service papers from the WW1 era. These, as you know, were bombed in 1940 and two-thirds destroyed. I couldn't see him in the Ancestry index amongst quite a lot of similarly-named men (but as you know, indexes are fickle).
Otherwise I confess I'm not sure where I'd look - the Anglesey County Records Office at Llangefni might be able to tell you what they hold, or maybe Rogin again might have a better idea than me.
