Curtiss Hawk 81 ( P-40 B) Walkways

Eduardo Soler

Recommended Posts

IIRC, the walkways were applied at the factory and I seem to recall reading that they were made of an abrasive material, like sand or silica, mixed with black paint and applied to the desired location. Depending upon wear and abrasion by pilots/maintainers and whether or not the wings were damaged and had to be repainted, the walkways weren't always re-applied. I think maybe our resident Curtiss expert @BS_w would be the man who can answer your query.



See the linked build article that has period photos showing the presence or absence of the walkways- best bet is to try and find a photo of your subject and hope it shows the wing roots!

on Curtiss H81/P40,B & C, the walkway was Linoleum sheet(Green Aero Floor) bonded to the skin and the edges were secured by metal stripes screwed into the skin.
On british and AVG airplanes the camouflage paint covered the walkways , so it is not easily visible..
