Possibly but unlikely that they would not have changed the filter caps since that time if it were kept in service, one would figure that someone would have tried to keep it going through the war years at least. The last Aerovox caps I ran into with a date code had hyphens between the numbers like 10-12-47 or something like that, but then again I'm not sure how long they used that yellow and black label or whether they always dated their caps. Since the set is from 1932 the originals would have been aluminum Philco brand ones, but if you have some older aluminum replacement style ones that will fit in the holes that would make a good substitute for the time being to fill the holes.
