I think that the thing here is, that most of these pistols will have some sort of resemblance to production pistols. so it is easy to jump to the conclusion that they could be some sort of prototypes, as with the case of my Britannia l bought of a dealer who had put it up as a prototype?. l bought it as what l thought was someone who just wanted to make a similar rifle just because he could. a case which we will probably never be able to prove. but it does make for a good discussion. l just love them and admire the thought and skill that as gone into making them by whoever.
