Hi Barry,
I have found Arthur Spiers on the 1911 Census serving with 3rd Battalion Worcestershire Regiment at Shaft Barracks, Western Heights, Dover (Dover Castle). Born Walsall 1888 abt. (aged 23, Single). Could this Arthur be your Granfather?
Regarding the chevrons you mentioned these were awarded to soldiers who served oeverseas. Red upto 31st December 1914 and subsequent years the colour was blue (1915, 1916 etc). So from the fact Arthur had 1 red (1914) and 2 blue (years unknown) we can assume he served at least 3 years oversas. He also had 1 wound stripe so at some point Arthur was wounded (could be a report in a local paper). The award for his MM in the London Gazette would have been printed some time after the award was won (time scale I'm not sure about).
Although Arthur was seving with the 2nd Battalion at the start of the war this does not mean he would necessarily have served with them throughout the war.
When he was wounded he may have returned home for treatment and on recovering been sent to another Battalion (without his service papers impossible to say).
Thanks for your offer regarding his discharge and character certificates. You may wish to send them with a photograph of Arthur in unifom to Louis the webmaster of this site to put on the photographs section. (My grandfather is on this section, he served with the 2nd Bn. and maybe he and Arthur knew each other).
If you wish to find out more on the 2nd Battalion (and all the other Worcestershire battalions) during the 1914-18 war then the following is a must for you to consult:
The Worcestershire Regiment in the Great War
By Capt. H. FitzM. Stacke, M.C.
(Your local library may have a copy but if not it can be obtained from The Naval and Military Press, not cheap but well worth it).
