Many thanks for this, I have found my great grandfather in your records. I found him last year as a P.C at Camberwell Station on the 1911 Census, which was suprise as I always though he'd spent all his early life in the army. I now know from your record he was in the met 1910-1913 (He was in the Army Militia 1906-1909, Regular Army 1914-1920..so it was evidently a fairly brief sojourn in the Police..perhaps it didn't suit him as much as the army!)
Anyway I do have another mystery, perhaps you can help with...perhaps not, but thought no harm in asking.
My late great grandmother, a Londoner, had a photo amongst her posessions of a Policeman. I have recently shown it to an 84 year old aunt, the last of the generaiton still with us, and she thinks it shows her uncle Alfred Ernest Woodhouse who was a career policeman.
I think I have found him in your lists:
Division E SPS 84123 Alfred Ernest Woodhouse 06-13-1898 to 16-06-1924
Forgive my ignorance, but I am unsure what the rank SPS means?
Would it match the man in the photograph we have?:

Also if yourself or anyone has any idea roughly when the photo might date from would be much appreciated.
Many thanks in advance.
