Looks like more clues are required, so - it's British, has two engines, was in service, one way or another, for over 30 years, in various Marques, with some, in specialised roles, still going a few years ago. There are a few still flying, and the type broke a few records, and was one of the first of its type to see active service, and the first of its type in another way.
Exported to many countries both within, and separate from, the Commonwealth, it's now a Classic, but could be a bit of a pig to handle, in its day.
What you are looking at, in the pic, is a major part of the airframe, but not where you'd expect - this part is almost hidden, but in full view, at certain angles !!!
