Here's a few pics to help a bit. The quality is weak and I am going to get abetter camera to help.
The first is the dorsal of a painted mini I got from a flea market, the second the ventral portion. The next two are close ups of the fore section of the secondary hull [note the small circular weapons bays in the tips of the wings and the larger between the wing shoulders and the boom] and the blurry aft secondary hull [the stern].
Ill try better pics soon.
Hope these help in your detailing?
