What is the weight of the fuselage (only) of the Boeing 747?
The fuselage weight for 3/4 of a 747-300 Combi minus engines, fuel tanks, seats, catering, cargo handling, navigation gear, control surfaces, pumps, hose is 70,000 lbs, according to Big Imagination, the people that bought a 747, gutted it and took it to Burning Man. The 70,000 lb figure was used by the Nevada DOT to determine the oversized vehicle permit fee. If you add another 25%, you come up with roughly 93,000 lbs.

In comparison, a A 747-300 dry weight with engines, seats in airworthy condition is about 384,000 lbs.

I know this only partially answers your question, but every other source I have tried features the Operating Empty Weight (OEW), which is a basic working weight for each plane variant.

Good luck finding a better figure. I'd love to know myself.
