This prototype Webley was one of just under 1,000 Model 1910 pistols produced by the company in an effort to get some military and police interest in their .38/9mm automatics. It was tested by a number of organizations (including, notably, the London Metropolitan Police) but not adopted by any. This particular one includes a number of unique features, most notably the lack of a grip safety (which was otherwise a standard feature in the Model 1910).
