I'm sorry for you about the leukemia, that's frustrating. Hopefully you'll recover back to normal.
I'm curious if you have prices for the Wurttemburg helmet with the red plume on your top shelf. And the Bavarian felt helmet also. The Prussian M15 looks to be in mint condition from what I see of the outside of it in your photo.
Hi Stuka F, Thanks for your interest. I think the grey-trimmed pickelhaube is sold. I'll let you know if the deal falls through. The cost of mailing the ersatz pickelhaube to France using US Postal Service Priority Mail would be $63.20. If there are transaction fees or if insurance is desired, then that would be extra.
