that´s a very old logo of "Siemens & Halske" (1847- 1966), later Siemens AG. Their passive parts are now "epcos".
I would say it is a foil-cap of 0,1µF with max 250 Volts DC and K means +-10% tolerance. Can you test them?
MAC should be the dielectric, but not identified.
Sorry, too young

Regards, Onra

best to cut one open and check for foil vs metallized? Or was the foil more common back then? Meaning, metallized being non existent?

Quite good for some caps with more than 20 years old.
