Overall it's not bad, and the only GR3 (in 1/48th) around. Surface detail is engraved, although a bit soft in places as far as I remember, as the model is now with the guy who commissioned it.
To do it properly, the auxiliary doors around the intakes need to be opened, and the canopy needs the extension frames on the sides, with the corresponding alterations to the top of the intakes. Otherwise, it should really be posed in the closed position. The kit has a lot of peotential for added detail, and turns out quite nice, although mine was more or less OOB.
It's out of production, but King Kit still have some I believe. Nearly got another to do as a Germany based ship for the Cold War GB.
