The Creed 444 scanned manual I have says 'ITT Creed' on it (and the
address is given as Brighton, not Croydon). I think ITT owned Creed at
that pont

The Creed 444 can also backspace the punch (and will use unpunched tape).

Yes, the main use of this facility was to immediately correct a typo
by backspacing the tape and overpunching the incorrect character with
all holes. You didn't need to rewind the tape if you only have 1/10"
of it to bother about.
