Can't believe they haven't sold the remaining windows yet... other than that, it ain't worth much. Can't hurt to ask...

But a word of caution: to use this bit of fuselage, you will need to build or obtain a base, some doors, a panel, seats, and a projection-screen setup... and everything you do will be dictated by the dimensions of that  fuselage.
Might be better, in the long run,  to start from scratch, or hold out for something more complete.
