Actually it may have been an original part even if it did not have the Philco name on it, the model 76 (Canadian 46-1201) had two Sprague caps it in and they were original as far as I could tell, one was inside the cardboard sleeve covering the wave trap. That set still had the original electrolytics installed under the chassis and it did not look like anyone had ever removed the chassis from that cabinet, to remove the chassis from a 46-1201 is a bit of an affair. I think that in the post war years Philco may have been buying capacitors from outside sources to keep up with demand, that or Sprague manufactured Philco labeled capacitors for Philco in those years, I know that prior to 1938 they made everything in house except the transformers and tubes.
