Gads - almost two years have gone by since this original thread of mine. I am still working in my spare time on the various F-4 versions with correct serial numbers and markings - I am finalizing an F-4B and F-4E again based on the original work of Dave Hobbs. If you liked my earlier F-4C versions, you'll like these. I also passed along an F-4D model to X RAY soon to appear here to go along with a project that he is working on (although I just found a few errors on the model).
If you need them for SF2, you will need to adapt them yourself though - I stuck with the 1st generation series. In the meantime, the Mirage Factory ARN-101 version of the F-4E is still very good and highly recommended, and like Dave said, they are still available here for both series, and you can't beat the superb hi-resolution skins and markings that Sundowner and others have created for them.
