Hard to tell if different from a Dalesford but they do look like very similar frames. I've not seen doped fabric or paper pulp bass drivers like these by them, but the picture in the link looks like it might be paper too.

Assuming that's an eight inch unit, apart from the smaller diameter dustcap, it looks just like the Mordaunt Short DSB 208 driver. Could be a version made and bought in just for this speaker.
Naim used one with no dustcap.
It is impossible for anything digital to sound analogue, because it isn't analogue!

I do't think any speaker companies made their own driver, but that Mordaunt Short driver rings a bell, but the terminals look different..
I like these sort of puzzles. Could be KEF B200 SP1014 or Dalesford D50-200. They look like the same chassis.
I think Dalesford were a bit cheaper, so popular. But the paper cone IS odd. MA used KEF SP1014 in the MA5 which was closed box.
The KEF was 210mm top to bottom. Easy enough to find the datasheet. Since the basses aren't in rebates, you could fit almost anything.
The mids look trickier, and maybe Beobloke has some ideas. But again you just need to find something that will fit. Presumably they have a little enclosure.
Well worth doing. Sort of project I like. Wilmslow Audio have some affordable replacement drivers. Falcon Acoustics have some Dalesford stuff.

Those Mordaunt Shorts might do the job, Geoff. You could always contact the seller and ask for some measurements.
Wilmslow have a Monacor Midbass Driver that ought to fit at 210mm too:

Any ideas on the mids? Some measurements would be useful if you need ideas.

Think the bass unit chassis are KEF, special paper cone though.
