Googling "Turnell & Odell" and Lathe came up on the second page of findings with a page from I think an in house publication showing one of their very early lathes.
I see that there is an Odell still as Managing Director, so he's the one I'd target for information as it's also his family history.
I did wonder if it was a Jarno or B&S taper, but your measurements don't tie up with either, so it may well be a custom one. I've not done the maths, but does it work out to be whole degrees or perhaps a recognisable fraction of an inch per inch or foot ? Don't rule out metric measurements even though it's an earlish English lathe.
(Tapers less than 7 degrees 'lock' and need a clout to release, whereas those greater than 7 degree self release)
