It is, Sam. Wright and Weaire sold decks to other manufacuturers as well as using them in Ferrographs.
I spotted the one on Dr Who - looks like the same deck as the early Ferro - Series 2 (?) that does not have a counter and the main knob is black - no 'window', and head cover slotted for tape.
Our tape experts will probably aid by fading memory on these.
