Sounds like a 47µF, 10v and 33µF, 16 volt, both with 10% tolerance*. A dual cap, as mentioned, extremely common in "can" form in the 1950s and 1960s, often with two, three or as many as four sections in each cap. Most "All-American 5" table radios had a two-section filter cap, maybe 60µF/40µF with a 150v rating. Some were above-chassis-mounted cans, others were axial-lead units below the chassis.
More recently than 1970, I've also seen three-leaded caps where two leads were the cap proper and the third lead was the "can".
*10% tolerance for an electrolytic is not the norm; they're usually specified something like +80/-20% as power supply filter caps are used as bulk capacitance, and the more the better.
