The register is more important than the threads, the important place to measure (with your gauge) is the inside of the taper.
Fix it to your lathe turn the spindle by hand and mark on the out side of the taper the point of maximum needle swing.
Take the ER chuck off the spindle and then screw it back on and measure it again - see if it coincides with the first mark.
If it does then the register is fine but the taper isn't coaxial to the cl [just for Mayhem] of the spindle.
A good place to start.

DaveH, if by register you are refering to the face of the spindle shoulder I admit that it looks fine but without register to the unthreaded part of the lathe spindle (between the end of the threads and the shoulder of the spindle) the device will not run concentrically. Especially in light of the sloppy female thread of the piece of crap.
