UK PhantomsAfter !

DECM is the long bump fairing along the outside of the intakes, with the black bump towards the front,,,,,,,,,they were on the F-4J(UK) when the F-4Js were pulled from storage and refurbished,,,,,,,so, the fairings were left there even though they were empty, when the jets were shipped to England

slime lights are those greenish-yellow formation light strips that sometimes appear on the tail, nose and fuselage of different versions of the Phantom, there were on the F-4J(UK) in the same pattern as the F-4S lights, and the F-4J(UK) was the only J version that received them

what is a decm conduit or a slime light, i have decals for all 3 varients

which of the three Phantom versions do you have "late decals" for?

if the FG 1 (or F-4K) or the FGR 2 (or F-4M), then in 1/72 scale you want to find the Fujimi kits, those are definitely what you want if the jets have the rectangular additions on the tip of the tails

if by "late" you mean the F-4J(UK) versions,,,,,,,,those can be made from any 1/72 F-4J kit from Fujimi, Hasegawa or Monogram,,,,,,,,or you could look around for some old Esci/ERTL/AMT kits,,,,,,as long as you add the intake DECM conduits to your model, and the Slime lights, but, with NO slats on the outer wings
