I was thinking more of pre and immediately post-war radios, on which the measurements would most likely have been made with an AVO7 or similar meters. I don't own anything that old, but over the years have repaired quite a few sets dating from the 50s for other folk. Where I used to work from the 70s to the mid 90s we had both an AVO7 and 8, supplemented later by a Philips DMM and a Fluke 75.
