Propellor Blade ID?

Hello, Just a quick question, i’ve had this Propellor blade for over 20 years, and i was wondering what it may be off? If i remember correctly, it came originally from a museum, and i bought it off an aviation dealer, can’t remember his name, but i’ve seen him at shows in the past. It did have a base on it that said propellor blade from a Spitfire MK? can’t remember the mark i’m afraid? Only after an ID, as was looking into selling off the blade, and to see if you guys could help me out at all?

Cheers, Graeme, Essex, :o)
