Well **** me gently - this is a truly stunning build Andy, more so that it's such a complex and, for want of better words, awkward b*gger to. first. assemble, and then paint and detail.
I remember doing the Airfix 1/72nd scale kit, back in, I guess, the very late 1960's, with a 'simple' splinter colour scheme, and still recall the problems of painting around struts, undercart etc - with a brush, before airbrushes were readily available at less than a King's ransom - and that was more than tricky.
Top marks my friend, and you can't better this, - surely ............. (expecting an 'Airplane' reply !!)
