Thanks for the pics, lajntx. I'll take a look at the kit and the pics and figure out what I'll need to do. The rails around the plane weren't there last time I visited the museum. If there's anything I need that's missing from those pics, I guess I can contact the museum and ask about permission.
One big thing, though: maybe I shoulda looked first before mentioning the bright idea. From a quick look at the pics alone I'm thinking one modified bay on a SF kit may not be enough before trying something like modifying this kit. Of course, one doesn't get experience from not trying and this thing has been waiting for something to be done for 30 years or so...
I guess since this is just for fun I should go for it and balance doing what I can to make this a decent display for the LHS with accepting that it's not likely to end up with competition-level accuracy and detail.
