pictured is my late Uncles (Edward Lee Millhoff of Sidney Ohio) helmet he wore while fighting in Europe during WW1. i recently acquired it along with two of his guns that supposedly he was issued some years after the War for taking care of "varmints" that were a problem where he was stationed. the guns i cleaned the best i could and now i need to figure out how to deal with this rusty helmet. the guns (Winchester 9mm shotgun and .22 rifle) were stored at several locations but the helmet was kept in a musty basement giving it the rust it has now. its not all the way through rust, just on the surface, and was hoping for some input on what i should do with it. was thinking about having it sandblasted and re-painting it the original color if i could find the color. i beleive the outside of the helmet was painted over at one time but am not sure. about a month ago i give it a good coating of Kroil and havent done anything else to it.
