The consensus seems to be that the undersides of British a/c were
fabric treated with clear dope and the color ranged from an
off-white to a buff to a yellowish tan, depending on which
particular airplane you're talking about or who you are talking
too. I don't think I'd tend to get too dogmatic about this
particular subject and just about any color in the range suggested
is probably right for at least *one* aircraft sometime, some wheres.
