Hullo everybody!
Matt,
If my description below fits the bill, then fine; if not, then my apologies.
Solid etched wedge-shaped blade including the letter S (SARAWAK) within Brooke motto (DUM SPIRO SPERO), the reverse with S within a wreath of oak leaves, panels of floral scrolls.
Solid brass gothic-style half-basket hilt, also with S within motto surrounded by oak leaves, in low relief; fish-skin covering.
Brass-mounted black leather scabbard. Chape.
83.2cm; 32 3/4in blade.
It was made for Meyer & Mortimer.
Best,
