The WW44 is schedule to appear in Flying Models some time this Spring. I don't have an exact publish date. The short kits will be ready when it hits the news stands. Apparently there was a rash of Golden Age Racers/Planes so Frank is spacing them out and I'm at the end of the list.
As far a B-29 kits go, the foam is cut by Flyingfoam.com and you order directly from them, and I've just been offering the vacuum formed nose and nacelles. Because the nose is such a deep draw, I have them professionally made. The B-29's are a slow seller, and I don't plan on stocking parts. it took me a couple of years to sell my last batch, and that's a lot of money to lay out. If you are really interested, email me and I'll see if I can get one or 2 sets of parts made by my supplier, rather than 10-20.
