I have the rarest U-Boat model ever (one of one). It's the Tehnoart U-525 (my new username, formerly snegron). It's a mixed media kit, 3D printed everything, TONS of PE and cast brass, MUCH higher in quality than the Revell U-190 (and differences based on it being U-525, different schnorkel and many other differences). They sold them pre-built and painted but I got them to send me a kit, along with U-505 as they were selling 11 of them as unbuilt kits. For years I was "the only kid on my block" with a 1/72 Type IX (LOL)! I paid $650 for U-525 many years ago and wish to sell it. If you're interested, PM me or email me at scottnegron@comcast.net. I can send pictures of the parts, and the instructions (once I find a CDROM to copy them as that's where the instructions are and CDROM players are like VCRs now)!
Thanks:)!
Scott
