Hmmm, great question. I've got a Hase 104 G?? in the "to be built"pile, but my Italian bird will be for show and go, no stores. I've got some leftover bits from somebody's low budget 104 (repop of the Lindberg??), built a few years ago for my nephew as a 'play with it' version. The only thing that comes to mind from that kit other than some Sidewinders is a practice bomb dispenser.
As I recall, Belcher Bits had some 104 goodies, but that might have been only 1/72.
I'll root around and see if I can put some details on what the other kit was, and see what parts I might have laying around.
Good Modeling,
