Manufactured in 1939. "Eagle/N" commercial proofs with added "eagle/359" Waffenamt proofs. This exact pistol is mentioned by serial number on page 48 of Jan C. Still's book "Axis Pistols" in which it states, "*Serial number 184894k is C/N proofed and E/359 accepted." below a chart of reported serial numbers and serial blocks of Walther PPK Army variations, in which this example is reported as an outlier in that it falls far below the typical known serial numbers of Waffenamt proofed Army PPK pistols. Absent magazine.
