Brilliant stuff Gary! Thanks for that, it's saved me a job!
Chook, work off the pics Gary posted, but note the following.
On the first pic of the steel, 'tear drop' tank, the pressure line is shown curved forward and down; on WW2 aircraft, this went into the wing.
The position for the entry point of this line is shown as in the second pic of the 'paper' tank. However, on WW2 Mustangs, on the 'tear drop' tank, the actual pipes were rubber hose, with a metal pipe and union ('Jubillee Clip') at the bottom, on the tank, and a shorter pipe with the same clip on the top, wing joint. This was to allow easy separation when the tanks were jettisoned. The joints were similar for the 'paper' tanks, from the point where the main plumbing bends up towards the wing, with the remaining, longer plumbing in metal, as per Gary's pics.
Note that the pic showing the empty pylon, shows the sway braces without the stabiliser pins - the metal rods that protrude through the end of each 'fork', with a small circular pad on the end which contacts the tank. These are included in the Hasegawa kit and, even if the tanks are not fitted, should be in place.
I'll still post the pics taken in '45 at Duxford, but Gary's pic are far better than any of the drawings I could provide.
Note also the angle of the pylon in Gary's last pic - it is mounted to the vertical datum, which means the tank would hang square to the pylon, not parrallel to the line of the wing, another thing I don't have to check - thanks again Gary!
Terry.
