Hello,

From what I can tell, these parts are not generally interchangeable.
I have a Dalton 7" (number 6125) and the three jaw chuck that isn't
running true (after 100 years, no surprise...) and have been looking
around for jaws or chuck to replace it. Nothing I've found fits - even
the 1.25" - 12 spindle thread seems to be bespoke. Let me know if you
find something!

=============================

You buy a blank, unthreaded, chuck backplate and use the lathe to
thread it to fit the spindle. Then you match the front of the
backplate to the back of the new chuck.

You could practice threading a pipe fitting before risking the
backplate.


Back when I was an apprentice boy no 3 jawed chuck was considered to
be perfectly centered and one always chucked up a larger piece of
stock to allow for a "truing cut" to ensure the work was running true.
Things shore have changed but a 4 jawed, independent chuck and a dial
indicator was the only method of ensuring that a work piece was
"centered".
