A friend of mine has found this blade in the loft of a deceased relative and wonders if anyone can identify it. The blade as-is (from where it is sawn off at the root) is just under six feet long, around 10 inches chord at the broadest point and "probably wooden". The root shape suggests (to me) that it's from a VP or constant-speed prop, so I was wondering if it was one of the compressed-wood (Jablo?) props fitted to some RAF aircraft in the early 40s. At six fee long it's too big for most of the fighters, but perhaps from one of the bombers? Do the numbers mean anything to anyone?
Just under 6' long and 10" chord at the widest point
TIA,
