the bottom bracket was English threaded, however.. (loosened counter clockwise)
CCW to loosen which cup?
If both then that's regular RH threading to both cups and indicates a FR (or Italian but that's not gonna happen) BB.
If you meant the NDS cup then CCW to unscrew is an indication of ANY threading: they ALL unscrew CCW.
If the DS cup it should require CLOCKWISE turning to unscrew the LH threaded cup for a British (or Swiss) BB
If you have both cups removed then TEST the BB shell with a known BSC (British) BB unit, but depending on brand there could also be markings on the cups which tell you what threading is used
