Thank You laEspadaAncha, unfortuantly to my eyes the appaling fit of blade to guard & hilt to guard as well as the use of brass as a guard to me eye looks even without the late font looks to be more likely 1970s Pakistan made item, rather than 19th century Sheffield
Perhaps I am wrong though?
I would recomend Bernard Levines forum on bladeforums for a more "solid" opinion though, Hes an ornery old chap but has a great knowledge of old Sheffield pieces. { As do one or two others there including a chap who now a collector was a cutler in Sheffield many decades ago.}
