November 1975 P4 in pristine condition. I'm guessing it's #702 of the 5200 made. P4 production started in October 1975, with the earliest serial number I have seen being 600365. The earliest November 1975 serial I have seen is 600625. All my Walthers, including a July 1943 AC43, 1974 commercial P38 fat slide, 1977 BW-issued P1, PPk/s, 1975 P4, 2022 PDP, 2007 P99AS

Your serial number 603109 has a 12/75 date, but it falls between and 602944 from 1/76 and 603441 from 1/76. I have also found 604294 made in 12/75, but the serial number falls between 604063 2/76 and 604555 3/76. I also know 604702 was made in 1/76 by Manurhin and falls between 604659 3/76 and 604772 2/76.
