Without seeing the propeller, or knowing its size, I guess we’ll all be struggling to guess what it would be fitted to. Would love to see a picture.

I suspect from the ‘Compregwood’ name, that the company made propellers in a similar way to that patented by Hordern Richmond in the UK. The main part of the laminated wooden blades were bound in fabric then heated and compressed to impregnate then with acetate dope.

It made for a light, strong and weatherproof propeller without having to resort to expensive imported woods such as Mahogany. But it means they’re a beggar to restore now!
