Were the original prop blades ‘plain’ wood, or were they resin impregnated also?

Thank you

The originals were indeed a resin impregnated compressed multi-ply material – as stated earlier. The modern Spitfire prop blades are made in Germany largely to the same recipie!

I’m just reading Rotol, The History of an Airscrew Company by Bruce Stait at the moment.

A fascinating book – well worth reading 🙂
