I guess I would also question why someone would have the name of a maker engraved who has long been out of business, if he were trying to fool people. The origin would be brought into question quickly when the date-specific proof marks were seen. If I were going to try something like this I would pick one of the numerous makers who were actually in business durring the time of the proof marks. No? I would have guessed that British criminals would have been smarter than this.
I will get some close ups shot for anyone who wishes to see them. See prev post for my address.
