The biggest Dave Graffam model I've built to date, and it's very imposing. Marginally more fiddly than most of the others I have, but it won't be a challenge if you're patient and do each stage in order. Around a dozen pages, plus a couple of reinforcement pages (I'd suggest doubling up on some of these for extra rigidity, but it works perfectly reasonably as is.
I've got around 20 of his models, and I am very impressed with this one.
