Modelbrass is still selling decks. I bought a deck for my Robbe U-47 back in June this year. I had a hard time contacting the owner. The email address at the web site is "NO" good. The owner told me that he doesn't even look at the incoming email. The best way to contact him is to call the phone number listed at the site. And leave a message with contact info. The voice message will say something about car graphics, don't let it fool you that's Modelbrass. I do have a email address to contact him, but it might be his home email, so I don't think it's a good idea to give it out.
I bought a VIIC deck for my boat cost $165.00 with s/h. VERY NICE deck, well worth the money.
Receiving time after ordering was about 4-5 weeks. Deck was mailed flat sandwiched between two pieces of wood.
Also part of the kit was the extension for the wintergarden, hatches, brass screws, brass tubes for the bollards.
Hope this helps anyone building the Robbe U-47. I am new at this "New Hobby" Going to start building after Christmas. See Ya, GawneFishing
