Measures 2.875" by 4.000". Made from .032" satin aluminum. Has removable protective film on face. This data plate is very like the original equipment item that was used on B-29 Superfortresses and late production B-17 Flying Fortresses. If you prefer an unstamped data plate, we also stock those. You can have your jeweler or trophy shop engrave it for any aircraft you like. Choose the unstamped option at purchase. Made in the USA.
