I looked into rocket rolls a while back, And I'm sure I saw a page where a guy got one of the earliest greco Vs (quite similiar to this) but had to modify it because the neck pocket angle was off. It was probably just the first few weeks of production, but I wouldn't spend £600 on a model of guitar I didn't know well from the other side of the world.
On the other hand, the seller seems good, and if you knew someone over there who could try it, go for it.
