Thank you. Here is the pickelhaube. It may have been on its side and crushed somewhat in a box. I want to open it up a bit. My strategy is to keep it on the hat block and leave it in the sun to warm up for a couple of hours.I suggest that you go to the Restoration Section and take a look at the many posts there. I have provided detailed explanations and photos of many of my restoration projects which should help. Last, post some photos here so we can see what has to be done. Again, good to have you with us.
