The Mr. Paint MRP-169 Light Khaki Avia B-534 would be the good equivalent. However the Gunze H-80 seems to be fine but it is a little bit too dark. I would add some of yellow paint to the colour. The another paint that can be used is Gunze (Mr. Color ) C54.
But if you don't want to mix colours you may use either the Gunze H-81 or Gunze (Mr. Color) C55.
Anywy, the old KP kit instruction says it was the FS 33070
