It actually looks like the High Planes kit of the Mustang World Jet racer, I've got one half built somewhere (it got packed away when we house moved and it's still there
) I might even hazard a guess that the flaps is something you can buy from HP too, pretty sure I've seen that on their website.
The cannon come from the Italeri Mustang Mk.I kit. Got a couple of those too --, not sure on the tanks though.
I've built three, four HP kits, they're not bad but they're not for the 'shake & bake' crowd, you actually have to apply your modelling skills on these ---
Couple of pics of HP kits I've done below but I've got loads of them in the stash
