Army Ordnance Store Corps 1891-1905

[orm1]

Been doing a bit of Family History Research and found my Gt Gt Grandfather was in the Ordnance store Corps from around 1891 when he was in Aldershot till at least 1905 when he was in Gibraltar. So I was hoping their is some miniatures to represent him and that you good people would know where I could find them. And also what the uniform was like.

Grateful for any help or advice
