With the brakes applied the hub is locked more or less solid so actually observing kingpin movement. (perhaps outer race which seldom at fault)
The Seven races are very generously proportioned and actual wear is normally insignificant so the play should remain as new, almost none. But movement of the bearing in the hub is common thru having not been clamped at some time due thick gasket, ommitted steel seal washer etc. Remedies of varying crudity, including centre popping, solder, fibregalss smear etc. Not prudent to loctite race into both halves. If properly clamped needs only be tight in one. Depths and protrusions can be measured.
Modern testers are accustomed to moderns with no play. Older taper rollers, often/normally loose on the stub axle, upset them. On my 1960s car to avoid inevitable argument I maladjust tight for every test. Otherwise would have replaced umpten times. if a tester thinks the car has taper rollers he should accept considerable play, but will likley accept little if knows they ball races.
