The script editor for Timeslip was Ruth Boswell. Scriptwriters: Bruce Stewart, and Victor Pemberton.
Because of a technician's strike, many episodes toward the end of the series were made in black and white. In any case, it seems that the original masters of the series were wiped in the late 1970s, and that with the possible exception of one episode the only surviving copies are black and white kinescopes.
