Very early cyqs (serial number below 500 and with an early frame) will typically have some Walther (E/359) inspected small parts. Walther is the only maker to serialize magazines and they stopped that in early 1942. No cyq was produced with a rectangular firing pin. Nothing made after mid 1940 will have a rectangular firing pin if it is an original gun.

Rectangular firing pins were only used on very early Walther zero series and very early HP P.38s. That hump started being used in mid 1943. The one in the SC is an early frame without that hump. Your gun has a late variation frame with the reinforement hump where the trigger axle pin goes through the frame. On the SC gun, the number is on the rail that is in line with the trigger axle pin.

The position of the frame serial number on your gun is immediately below the slide in a milled recessed area. On your gun, the slide serial number is below the 'cyq' stamp, on the Standard Catatlog (SC) gun it is right above the slide lock lever, further to the rear. Hi Shooter13, I have the same Standard Catalog that you quote and if you look carefully at the position of the numbers, they are not in the same location. This is where I got my uld you please quote your source so that I can verify your information. (Also not shown in the pic ) is the last two digits of the serial number (46) on the widest part of the trigger guard.

An eagle over a circled swastika and the eagle over 359 appear on the slide above the grips on the other side of the slide ( not shown in the pic ). The serial number 246 appears again on the locking block under the barrel. Both magazines are numbered with 246 on the bottom front and the eagle over 359 appears on both of the magazines spine.

I have also read ( internet ) that the rectangular firing pins were found only in the early low serial number ranges. Top of page# 127 (same book ) has a picture of an example slide with markings in identical positions to my firearm as shown in the picture. Value depends on markings and an expert should be consulted for values. 'cyq' (1st variation) The first 500 of these guns have the eagle over 359 on some small parts and command a premium. The serial number is 246 ( the x value is the last digit of the serial # I was excluding in first post.ie not an x block ).and my source is a book that I have, in particular: Standard Catalog of Military Firearms The Collectors Price and Reference Guide 3rd edition by Ned Schwing published by Gun Digest Books ISBN 0-87349-902-6 mid right side of page# 126 (under Spreewerke Military) quote.

I'm not being critical, just thought you should know, in case you didn't already. Spreewerk magazines were never serial numbered when originally made so those numbers were likely applied post-war. Here is a link to one of my cyqs so you can see the location of the original numbering. Your's, being an 'x' block (assuming that is the original serial number) would have been made in late 1944. The E/359 is the waffenamt for Walther and only appeared on cyqs on very low serial numbered guns made in 1942. It appears the gun has been heavily buffed, removing the old markings and then remarked. Hi Shooter13, Just an FYI, the serial numbers on the frame and slide are not in the original locations.
