Deaf Miners in Bishop Auckland ca.1920

Time constraints mean a picture post only today.  By an unknown photographer, but in the Oxley photographs, is this nice image of Deaf miners from ca. 1920.  Someone out there may know who they are.  Where are they working?  I would guess they are loading mined coal onto the narrow gauge railway before it went on to a larger railway wagon.  If you can tell us anything about the picture please tell us.

 

I see there is still a Deaf Club in the Bishop Auckland –
