We have established that 2nd. gear works out under load on both P.II and Peregrine. As well as altering the box on the 3 Per.II for France will you please modify the new 40/50 box in accordance with E's idea of a 1/100 tube on the clogs providing of course a suitable thrust face in the gear. We would then fit the box to 19-EX. before it goes to France. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
