F-51 Mustang External Tanks

Hello, I’m building the Tamiya F-51 1/72 kit and trying to duplicate a picture of one that was deployed to Iceland in late 1952.
What’s got me stumped is the size and shape of the external fuel tanks.
I have a couple of books with other pictures of the Mustangs in Iceland also with the same tanks, but they don’t mention the size or where they came from.
They are definitely not the same as the ones you typical see Mustangs carrying… i.e. WWII era drop tanks or the larger paper mâché.
Any thoughts or ideas would be appreciated.

It is likely they are something from the Korean War with an extended middle section, called Misawa tanks.
