Groak brothers service in India

[Derek]

I have information on Patrick Groak, regimental number 853, who served in the Worcestershire Regiment from 1884 to 1891 and then in the Army Reserve Sec. B from 1891 to 1894. This included service in India from September 1886 to November 1891.

I am now trying to find information on his brother James, born Dudley in June 1858, who also served in India.
Unfortunately, I could not find any service record for James at the National Archives at Kew.

Can anyone help me in finding James's service record ?

Derek.
