Today I found a man who has a few original helmet parts and two incomplete helmets. What he has is three eagle plates with wide spread wings, a Artillery round topped spike, a few rosettes and a long gold braided cord and a silver cord. Do these parts have much of a value ? I can get them in a trade deal but don't have any idea of their value. The two helmets. one looks like a costume company or maybe movie studio had it, the body is pretty good but has been painted black, the spike looks home made the only original item on it is the eagle plate..liner is mostly gone. The other is not bad, it has a nice officer spike and back rib, the metal around edges is good, the body is good there is no plate, liner is fair. Thanks for the help !
