This one doesn't have cylindrical rails but it does have a buttress thread. It's one above the camlock nut type but one below the modern qr system.
What does it have, and what do you class as the modern system?









I was doing so well too, I sold a Woden wood vice the very day before I bought the Parkinson! Some pics of the Woden for you, I've never seen another and only a written reference in the catalogue. A very poor design, very flimsy and a complete pain to reset the toothed piece when (not if) it falls out.
