BE2a

[kiwi]

Not sure if this is the correct place for this question but , I have just looked at my photos from Masterton , and in a photo of the BE2a the underside of the fuselage appears to be a colour darker than the clear doped linen sides , is the underside made of wood ? Ply ? Or is it also linen but dirty than the sides ?

Hi Kiwi, the underside was also doped fabric, so could be a combination of dirt thrown up from landing and taking off and oil?
