Metal or wood?

With the butt end of the blade missing it would be hard to tell what it could be from.
From what I see it is an aluminum blade, right hand rotation. From the length that you give 2.25 m, which is about 7 feet 4 inches. Add the blade butt to the center of rotation would add about another 6 to 8 inches, so the propeller diameter would be about 16 feet or greater. From the shape of the blade it has similar looks to a B-29 propeller blade, based on the diameter, as there are not very many propellers with that diameter. Example the P47 was around 13 feet in diameter.
If it was a blade from a B-29, the width of the blade about 30 inches down from tip of the blade would be between 11 and 12 inches wide, if it was a full diameter blade.

The length that you give 189 cm, is close to 6 foot 3 inches, plus the missing portion would be a 13 foot plus diameter. The shape of the blade is not as I see to be the shape of the Hamilton Standard blade that the P-47 used. The width that you gave 30 inches from the tip is close to what a P-47 would be, if it was about 13 feet in diameter. There were many different aircraft that used the same or similar part number blade as the P-47, the F4U Corsair, the Grumman TBF/GM TBM, the C54/DC-4, to name a few, so it is hard to tell without any actual marking from the blade butt which is missing.

Can you provide a good photo of the hub end. From the photo you provide it appears to be Ham Std but a good photo would clarify that. Also look at that area and try and find numbers. If even a partial blade type number is evident it would narrow things down considerably and Michael as our resident prop expert would be able to translate that to useful information
