Circle deuce is Sprague (their EIA code is 2....), 715P is the dielectric, c=custom foil, and the 22-7504-01 is the zenith part number. Last 4=EIA date code, beginning with the year, 78 an 82, last two are the week number...

715PC later became 716P dielectric, for pulse applications. 716P are all 800V, 1000V, 1200, or 1600V caps....
