Does this foil have a paper or cardboard backing? To me it looks like the sort of embossed foil that would have been used in a chocolate box, or some other packaging. My guess is that Philco was using the same logic they used when selecting tube lineups, it was whatever they got a bargain on, or could get in quantity when they wanted it. If they needed some foil for some reason like shielding, but could get embossed stuff off the surplus market for 1/2 price, they were not above doing that.
