This set provides belts for the F-104G using the Mk. GQ7A ejection seat. The F-104 also used a C2 ejection seat and one is provided in the Hasegawa kit I used (stock #PT 20) but the seats are very different designs and this set won’t work on the C2 seat. In general, the export versions of the F-104 used the Mk. GQ7A seat.
I would consider this a “must have” since the base kit doesn’t provide any kind of harness for the GQ7A seat. Eduard makes two harness sets for this kit, the FABRIC set reviewed here and SUPERFABRIC (Eduard #49 073) set that I’ll share with you in separate review. The FABRIC set is a little more difficult because you have small PE buckles and restrainers to thread the tiny belts through. This was my first exposure to this type of belts from Eduard. The details are very refined and the PE parts add a nice dimension of depth to the finished assembly.
