9718 Arthur Spiers MM

Having just left the Army after 36 years I now have some time on my hands and I am trying to find some more information on my grandfather Arthur Spiers.
9718 Arthur Spiers served in the Worcestershire Regiment during the period 1910-1920 and was awarded the Military Medal during the war. I have the following information:
1. I have his original medals including the MM.
2. I have his Original Discharge Certificate, Character Certificate and a few photos of him in uniform with his mates.
3. He was discharged from the Army on 31/03/1920 having served 10 years with the colours and 3 years in the Army Reserve.
What I am really looking for is his service record, his discharge certificate states that he also previously served in the Military Provost Staff Corps.
I would be very grateful if anyone could provide me information on his service record.
