Verlinden? Instructions? Ha! Their motto is "You don't need no
steeenking instructions!". They only supply a basic sheet or two with
their kits, but, as ajlafleche said, the picture of the finished model
on the box top is all you get with the figure kits. This is a book I'd
recomend, Osprey Publication's
US Army Air Force (1) (Elite)
There are some other excellent books out there as well. I have
one called Gear Up! Flight Clothing & Equipment of USAAF Airmen in
WWII that has lots of great pictures, including color pics of various
clothes and equipment.
You can find both at Amazon.
