Don't want to start an argument, and I'm sure Scrit will have a definitive answer, but I think it's actually a Coronet <Minor>, not the Major, which was a much bigger beast.
It dates from the days when Coronet were in Derby, and made a range of lathes, planers, bandsaws and semi-universals. I've had various of their machines, starting with a lathe almost identical to the one shown, but sold by Gamages as their own brand. The biggest thing I made on that was a spinning wheel (I bodged up an adaptor to hold the toolrest with the head swung forward). For a short time, I had the three wheel bandsaw that fitted on the lathe as an attachment. It was quite a good saw, but an absolute pain to set up on the lathe, so got very little use.
Then I bought a very cheap Minorette, which was the same headstock but with a very short bed and an 8" sawbench (bit bigger table than shown in your pics), basically intended to be used as a small universal. Tidied that up, and sold it at a reasonable profit! Lastly, I had a Consort, which was quite a neat little circular saw (8" blade) with a 4.5" surface planer attachment. It would also take the lathe bed.
As lathes, I reckon they were good (though I did finally trade my Gamages version for a Tyme Avon with a very long bed). Their strong and weak point was the tailstock, which on the smaller models did not locate positively in the vertical position. This meant that lining up head and tailstock was a bit hit and miss. Very handy for some tapers, though!
The earlier ones with a circular saw like your's were distinctly dangerous as the guarding was rudimentary (to be kind). A friend nearly had a very nasty accident bending too near the saw to look at the back of a bowl he was turning.
So, if I was you, I'd ditch the saw instantly, but use it as a lathe and you'll really enjoy it. If you want spares, Derek Pyatt (somewhere near Wolverhampton) keeps quite a lot, at a price. But since Coronet introduced the 3/4 by 16tpi thread for their headstocks, all the modern chucks etc will fit.
