I've got one of these as a WIP and one in the box. Both of my grandfathers worked for Rockwell so they had a hand in the B-1. I learned a little tip the other day: Don't glue the center fuselage halves together; rather, glue one half to the tail and nose, then glue the other half. This way, you have a gap to worry about instead of two steps. Good luck on the BONE!!!
P.S. The SRAMs are in the kit because the JDAMs weren't even thought of. At the time of the kit, the SRAMs were the prime weapon for the BONE. Also, sand off the bumps on the aft end of the nacelles. Those were on the B-1A, but not the B. Check out this site for some BONE accessories: Resin Sets for Modern Jets Also, there's A B-1B thread going on at ARC if you're interested!
*EDIT* Forgot to tell you, this looks great so far. Keep at it, I can't WAIT to see it finished!
