Greetings!
Just bought the Revell 1/48 JU88A-4 and I have a spare set of Eduard cockpit photoetch and Masks for a Dragon JU88A-6. Should I buy a new set for this kit or would the A-6 stuff work for the A-4. Any info would be appreciated.

Which Revell Ju88A-4 did you get? The newer ICM reboxing or one of their earlier Dragon reboxings?

If it's the Dragon reboxing, the aftermarket stuff you have should fit in just fine as it's essentially the same plastic. If it's the newer ICM kit, you can probably make use of most - if not nearly all - of the PE set (some trimming might be required here and there, though), whereas the shapes of the canopy parts might differ enough between the kits to justify getting a new mask set specifically made for it.

Many thanks for your advice. Yes its the newer ICM version. I was thinking the same about the photoetch cockpit but you are probably right, the mask I will buy a new one. No sense going cheap on such a nice kit.
