Army Form B.2056 gives a useful summary of a man's colour service prior to his transfer to the Army Reserve. In the case of Private Groves (above), his conduct and character is described as "Indifferent. Addicted to drink".
Brief service history details are given on the following pages, also a description of the man and his intended place of residence. It's a useful document and in my experience there are not too many that survive in WO 97. This appears to have been one form which the MoD decided could be weeded and disposed of, probably because the majority of the information included here is also noted on the attestation papers.
