As I recall, Francotte had a retail outlet in london in the early 1890's Most of the London marked Francottes I have seen were made to a bit higher standard than the normal but still quite high quality of the regular run. I have a "London" hammer gun that I use as my rainy weather gun; not because its a beater, but it is a bit shorter than my other grouse guns and is still quick while I'm in my Barbour.
