Victorian prison warders' uniforms

I began to wonder what Victorian prison warders would have looked like and discovered these fab images on the Internet. Althought they don't portray prison warders from Woking Invalid Convict Prison, they do portray prison warders of the same era.

The first image depicts Mr Lewis Cooke, his wife Mary and their three children. Lewis Cooke was a warder at Stafford Gaol between 1881 and 1891. The second image depicts a female warder at the same prison.
