This bit probably dates from the early 20th century.
One cheek is stamped "Eglentine" - a nickel alloy trademarked by F.Eglington of Walsall in 1905 It has flat cheeks with coiled integral curb hooks - the end of one of these hooks has broken off.
It has a straight mouthpiece stamped "Swales Patent" and "Pat16057" There are loose bit rings inside the cheeks - these are soldered in places - it is not clear whether this was from the time of manufacture or a later repair. The rings are also stamped "Swales' Patent"
