I bought this helmet from a coin/estate/junk shop a few years ago and have been slowly restoring it. I didn't know anything about the pickelhaube, so it has been a learning experience for me.
I'll post some of the photos that I took shortly after I bought it and then will follow up with some shots of how it looks along the way. I know the chinstrap is a repro, I'll replace that when I find one that matches the condition of the helmet. Also, I have not done any resewing to it as I figure that any mistakes that I have done so far can be reversed, but sewing is pretty permanent.
If you have suggestions/recommendations, please let me know!
