Does anyone happen to know what the airfoil used on the 30s era Handley
Page
Harrow was? A friend is scratch building a model of one and would like to
use the scale airfoil.

Unfortunately the Putnam book (Handley Page Aircraft since 1907, ISBN
0-85177-803-9), doesn't say. Neither do any of the other obvious sources I
have. Forgotten Bombers of the Royal Air Force, by Ken Wixey (ISBN
1-85409-306-1) has a relatively detailed description of the wing structure,
but not the aerofoil. However, it does say that "Dr Lachmann based the
cantilever monoplane wing on that of the earlier H.P. 47 general purpose
monoplane". Of the H.P. 47, the Putnam says "Lachmann proposed a low-wing
cantilever monoplane with a uniformly tapered wing of RAF 34 section". It
doesn't specifically say whether or not that was used, but it doesn't
mention that proposal being changed.
