I would call it about a "C" grade SLE, based on the modest engraving. That doesn't mean it can't have very decent lever work and fitting. But, it doesn't have the finish lavished on it for a higher grade. The Webley Screw-Grip is a workhorse, but was not, far as I know ever made into a best work gun. Manton's sold mostly in India, as I understand, and this would have been a very good choice for Brit colonist.
