We are getting a little bit off topic, but:
Actually, the numbers of all Es locomotives of SPAP railway were the following:
Es 701-702 / A. BORSIG, BERLIN - TEGEL / 1912
Es 711-713 / A. BORSIG, BERLIN - TEGEL / 1914 (later 7711-7713)
Es 721-725 / LINKE HOFMANN WERKE BRESLAU / 1925 (later 7721-7725)
Es 726-728 / HENSCHEL UND SOHN, KASSEL / 1937 (later 7726-7728)
701 was destroyed in the 2nd World War, so, probably in order to avoid having gaps in the number sequence, 702 was renumbered to 714, later 7714.
