Your scale masterpiece deserves a beautiful prop! Check out this press release from Vogelsang Aeroscale, who specialize in propellers for radial engines like the Moki (Vogelsang is an official Moki dealer).
“Designed and made in Germany, these propellers are of laminated construction using both a very dense mahogany as well as the finest dried red beech. This results in fantastic looks as well as superior quality and stability, effectively upgrading every airplane. They produce plenty of power without being too noisy. They are very accurately machined and require the minimum of balancing. We place size, pitch and the SEP logo on the back of the prop for obvous asthetic reasons. They cost from $24 to $185.”
