We might be on the right track in one answer

Is this second one a reheat Sapphire?

Handley Page HP.115 or Short SC1?

To the last two, sorry no (but the second photo is a reheat engine as you spotted.

The second one looks Russian...?

Wild guess, possibly the Sukhoi Su7 pre and post afterburner at Monino?

Neither of them are Eastern Block

So, should we be still looking for a British solution...in a British Museum?

Hmm...is this the start of a new thread? Shall we call it "Name That Tail Pipe" ?

Reheat, Sapphire? An unusual fit; – lets try a Hunter test aircraft with Sapphire or Avon, with reheat.
For the first jet pipe – it’s long, and not a true circular fuselage – Swift?

As an alternative, possibly linking the suggestions above - Supermarine 525.

Noyade
Yes that is correct but you might have crossed too many aircraft off the list!

Is it the Hendon Museum?

Clutching at straws. Location FAA Museum Yeovilton Aircraft Handley Page HP115 and BAC 221.

One out of 3 sir!

G'day Mel, I thought the HP.115 was eliminated when sabredog mentioned it above?

So maybe...

BAC 221?
Hawker Hunter?...

Fleet Air Arm Museum?

Hunter butt....

Or "Plug that Butt!"....:)

OOOh very close one type incorrect (but maybe not the maker)

Harrier?

The cheat is the missing engine!
I'm seeing it in the photos!

A Harrier with re-heat? That would be fun

Hawker P1052 (VX272) at Yeovilton
