Antique Carpenter's Square, set of three, wood, brass and steel

Description

Set of three matching antique framing squares in different sizes.
I don't know much about them, but f
rom the research I've done online, these seem to match others with descriptions claiming they are an English rosewood and brass right angled tool dating to the Victorian period circa 1880 or something similar. That would make a lot of sense since I inherited them from my grandfather who fancied highly valuable antiques with interesting stories behind them.
