Could anyone help to identify the uniform being worn by this lady ?, the picture hung on the wall in a friends grandfather's house alongside one of him in his WW1 army uniform, I thought it may be something connected with public transport, nearby was a railway line jointly operated by the midland and north eastern railway companies but I have trawled endless sClick image for larger version.
