This part-blade is in excellent original condition. The maker
was Maple whose decal is the best example that I have seen. The
red band indicated the direction of rotation. The engine for this
prop, the Rolls Royce Falcon, was made in both right hand and left hand
rotation so the prop had to match the engine. The black arrow
reinforces the point.

The chord of the propeller matches the four blade prop made for the
DH4 by Maple, drawing number AB2450.
