Iliad Design has released a new decal sheet in its 72nd scale line devoted to early P-40s and Tomahawks. This sheet provides you with 6 airframes, 3 in American markings and 3 in British markings.
The American options include a natural metal finish, an Olive Drab over Neutral Grey and a Olive Drab/Dark Earth over Neutral Grey. All of them sport red and white stripes in the rudder.
The British options include two Olive Drab/Dark Earth over Neutral Grey, and my personal favorite, Dark Earth/Middle Stone over Azure Blue in North African campaign markings.
The decal sheet instructions do not specify for which kit they are meant to fit (Academy, Airfix, AML, Hasegawa or HobbyBoss). That shouldn’t be an issue for most of the decals, with the exception of the red and white stripes for the rudder which might need to be trimmed to fit depending on which kit you are using.
