Checked out the yoke-no makers marks, just stamped "y-89" on the body retaining clamp (the larger clamp, not the tiny one that affixes the yoke to the crt neck). Pins 1&7 test right on 41 ohms, as per the schematic's call for the vert half. Pins 3,5,8 all test for continuity (short) instead of the 30 ohms per the schematic. I guess shorted horizontal section would give me the keystoned horizontal sweep, and perhaps crappy bloom-worthy HV. The cap in the windings is not shorted, btw.
I think I found a replacement on a certain auction site. The numbers on the SAMS pretty much match up (SAMS says y-41):

Or I could just wind my own if I can haul this thing from Hungary:

EricH: I pulled a known working 1B3 from my RCA and put it into the Olympic with similar results. As for the keystoning; it is a flat-topped pyramid shape-equally truncated on the upper left and right sides.
