There should be a stopped hole just to the left of the base of the 4-spur drive center. Insert the end of a shaft or bolt in it and use it as a lever. Apply an open end wrench to the spur center itself. The spur center will screw off toward you.

I think they used to have a special wrench that would fit in the hole at the shaft

I think J is probably right. A very few of the older lathes used
solid spindles and screwed on drive spurs and accessories. I saw an
old Walker Turner where this was the case, and the owner of the lathe
mistook the hollow end where the handwheel was mounted as a sign of a
totally hollow spindle shaft.

He beat the absolute hell out of that thing trying to drive out the
spur thinking it was a taper fit of some kind. Of course it never
moved. Being old iron he didn't hurt it, but he didn't get the spur
out either. He took the headstock to his buddy in the welding
profession who took it for granted that the spur screwed on because
that was the way his accessories mounted on his metal lathe.

He took it off exactly as J. described.

BTW, I had to do the same exact thing to a 30 year old Sears lathe
about 2-3 years ago. Liquid Wrench, a 12" pipe wrench and a 12"
crescent broke it loose.
