Thanks, lad.
Gondola does suggest itself, indeed, but I'm pants when trying gasbags. One can get by, I suppose, with stiff strings up to an imagined one.
I've pulled everything apart; neither I have had the 'croc gun', which is a bit disappointing. Other projects suggest themselves from that alone. I has rivets, it does!
The shark head and 'tiller' are easy enough to dispose, and I'm starting to think to cover one or other hole with boom to another hull. Blame Space 1889 Martian kites, of course.
Still, that wood grain...
Maybe paint grey with blue/black wash? Claim it's 'lift granite'?
