Bob, Take a look at this page: http://www.faa.gov/fsdo/PHL/airworthiness.htm As far as the "not specified" is concerned. I haven't been able to find anything about this. The only thing I can think of is that the aircraft are ex-military and the new owners haven't told the FAA what category they are registering the aircraft as.
