Looking for basic information about the firm and specifically the SLE Imperial model. I handled one recently and it seemed to be of very high quality. Is it generally considered a London Best gun? I can't seem to find much on the internet, and only one comment on quality. All I really know about the firm is that the founder worked at Holland and Holland about 100 years ago and left to set up his own shop.
Also this gun has a serial number of 16xx, so a time frame of manufacturer would be great. Unfortunately I don't have any pictures of receiver or barrel flats for proof marks.
Thanks.
