The Ju 88 A-4 should have had the broader VS-11 (compared to the thin cord metal VDM) propellers made of wood. The wooden propellers also had a final coat of RLM 70. The composition beneath was plywood with a very narrow metallic leading edge and a very thin metal mesh all over the propeller blade. Then everything was covered with a red-brown primer and finally coated.
Cheers, Azi.
Edit: PS: Fine model!!
