Charles and I seem to have gotten faked out with this one. I get the same resistance readings with a Fluke 77 using an early-production CT-100 yoke.

You may/probably have a genuine CT-100 replacement RCA-manufactured yoke. An other possibility is a yoke from one of the kit-of-parts RCA was selling to rival manufacturers for development purposes in late 1953 and into 1954.

Any indications of use?
