My gun is not a William Richards. Although it is in such poor present condition it's a bit hard to tell, but quality-wise I put it above a Belgian W Richards but beneath the Liverpool W Richards.
Somewhere on the internet I once found a posting by W Richards of Liverpool showing markings that would be found on all guns of their make. Was plain & simple mine wasn't among them. Mine is strictly a wall hanger, kept Solely for its sentimental value.
It appears to be well established that Clabrough did indeed build some low-cost guns carrying the W Richards name, so I assume mine is one of these.
