Excellent modelling here.  Plus great reference.  All pictures by Mike Garamond

F-102 Case X and Case XX identicaton

Here is a reference to the difference between the Case X & Case XX.


Check the Serial number of the bird you're going to build:

Case X (flat trailing edge wing and rectangular shaped aileron): Serial numbers- 53-1790 to 56-1316

Case XX (curved trailing edge and angled outboard aileron edge): serial numbers 56-1317 to 57-0909

Sometimes you see the Serial number with a "0" proceeding it (most of the ANG birds from the 70s) for example "0-70909" would be 57-0909.
