2 x one-piece, two-blade wooden props bolted together, so as a previous poster has said, it could conceivably have been installed back-to-front.
As for the effect of installing one that way, I would expect an appreciable reduction in thrust. Although the blade pitch would still be the same, the camber on the aerofoil would obviously be reversed.
Not to be recommended.
