Can anybody tell me where I can purchase the decals that go on the side of .50 cal ammo boxes? I've seen these on some 1/16 models.

Also, does anybody have a method for picking out the very fine letting on 1/16 .50 and .30 cal ammo boxes ...ie a very very small paint roller?? I can barely SEE it let alone "paint" it. My hands just ain't that steady!!
