Hub ID

[dharding]

Hi
I wonder if anyone can help me ID a hub that I've acquired.

Its made of 6 laminations of mahogany with 8 bolt holes.

On one side of the hub in large font is stamped the no. 5?06.

On the other side in smaller font is stamped
2744 DIA
18?? PITCH

Any help would be much appreciated.
Thanks
Dom

I don't think there's enough information there to know.

That's a very flat pitch for a prop of that length, and I don't see any propellers that come close to those numbers.
