I have an ft101b.? The case an chassis have different serial numbers.? I know it is a 101b because of the circuitry and the boards for a couple of the modules.? Find a service manual and look at the table showing which circuit board versions are in what 101 generation. Find instances where different circuit board versions change. Try to match yours up.? It may be confusing since some of the boards are interchangable...
Good luck!
