This 30 Luger 1920 Commercial Artillery Luger has the 8"" artillery barrel with the adjustable artillery rear sight. The chamber and toggle are unmarked and the only proof mark is the WWI era firing proof on the toggle breechblock. The left receiver side is marked GERMANY in fairly large letters. The gun is serial numbered 3468a on the front of the frame and 3468 on the left side of the receiver. The barrel is unmarked. The small parts, including the firing pin and grips, are numbered 68. The correct style wood base magazine is not matching. The gun has approx. 95% blue with the barrel finish thinning and approx. 85% straw. The bore is very good with frosting in the grooves. The matching grips are fine with just a couple of storage imperfections. The action functions correctly. This is a very interesting variation. How did it escape the crown over N commercial proofs?
