I was just going over the book I saw the refrence to ABOUT the early plywood drop thank( The Battle of Britain by Richard Townsend Bickers (pg6
and to my amazement there is a drawing of the 109e4 with a drawing of it's auxiliery equiptment and a early WOODEN DROP TANK IS SHOW THAT LOOKS EXACTLY LIKE THE PHOTO HERE!
Wish I could scan it in for you and show you the drawing but I have no scanner..
btw..the drawing looks more like the photo above then the heinkels d/p. BTW, do you know if the heinkel d/p is wood? It looks like a dent is in at the front it as if it is made of metal..
I know you don't believe my sources but one of the contributing authors to the book is Adolph Galland!
