Yep, it will be. I have the 'P' version, to convert back to a 'A-1' (the only kit I could get at the time, for the right price), and it has parts for other versions, including the 'A-1' rear canopy, with extra sprues for the 'P'. Annoyingly, the earlier belly cupola is included, but not the rear hatch for this ! Fortunately, I have a vac form cupola to either use complete, or just use the rear hatch.
