11/5/19 - This is an excellent example of an original and very late Walther Model 4. It is a 6th variation example, with rectangular ejection port and 'MADE IN GERMANY' export marking on frame. Dieter Marschall's book on Walthers has the final serial on Model 4 production as 493,700, which would mean this was one of the final 50 ever produced. The original blue rates at 96-97% with minor high edge and muzzle thinning. Excellent bore and grips. Walther banner magazine.
