Hi Mips.
from what i gather without reading the schematic( gotta dig it out), most readings/waveforms use the chassis as ground for the test equipment with gear this vintage.check the footnotes on the schematic-it should say if the voltages/waveforms are taken with repect to chassis ground.
from what i have seen from your pictures-the last problem is width...tv width looks acceptable-some of these vintage sets never had perfect width or control of width.
i would try retaking those waveforms with the scope set in the "u" (horz)range?
might see they match the expexcted waveform? iirc,1 horz scan line is aprox 63.5 us or microseconds or 1/15750
not sure at this point without looking at the schematic why you are getting 60 vac with respect to ground-i suspect you are using a isolation transformer while working on this set so should be safe but will get back to you once i dig schematic out.
is picture good at this point other than width being a little wide?
just some thoughts.
