Hamilton Standard Metal Propeller Blade

Metal 20th century Hamilton standard propeller blade with yellow painted tip and Hamilton standard stick to the centre. The blade is black on the reverse side. The propeller is bent at the end. With all original wear to the propeller blade, this is a great interior design piece. I am not sure which aircraft it would have been used for. Hamilton standard was founded in 1929, I believe this to be post 1940s.
