When you happen to have authentic u-boat stuff (overseas caps, real conning tower pictures of u-boats etc.) that you need to get rid of, then surely, I wouldn't mind taking over (part or) your entire collection for a very reasonable price on my part. But I also have plenty of u-boat stuff on offer, so trading for original cap badges is always an option. You are always welcome to email me at firstname.lastname@example.org. Thank you vm.
