Wow quick responses! I've been trying to find any info on personnel connection...this might be harder to find then I originally thought! I thought the same regarding the markings on the box (regarding the missing "Henkel" markings) Voidmaster, but the Navy base wasn't operational until '41 I believe. Would I be wrong believing that it may have been manufactured before the merger, but not issued until much later? What do you guys think? The value isn't so much as to sell it, I'm more interested in it just for the sheer knowledge and yes, how gently to treat it. You basically hit the nail on the head there.
I was thinking cleaning it with windex and metal polish first to see the situation under the rust that's there then go from there (ie pro hone)
