Dave,
The serial number is 449430.
They also have a correct WaA162 marked gun serial number 568197 which is a clone of my pistol 572362 in terms of how the marking is applied. I've illustrated the two markings below.
Here is the discription from the catalog for the fake gun and they are looking to get $1,100-$1,600.00.
A number of these pistols were built and used by the German army during the occupation of Italy in World War II. Some of these pistols, such as this one, were marked with the German acceptance stamp. The left rear of the frame is marked with the Italian Gardone proof over the Italian "crown / P.S.F." proof over "1940". Behind the markings is the German "eagle / WaA76" proof and the German eagle firing proof, marked on the left upper front of the trigger guard. The left side of the slide is marked "P BERETTA - CAL. 7.65 - BREVETTATA / GARDONE V.T. 1940 - XVIII". The right side of the slide and frame are marked with the serial number. Fitted with black textured grips with "PB" monogram at the bottoms. Complete with an unmarked green leather flap holster and extra magazine
It seems odd that they have a real WaA marked Beretta and a fake one and they are promoting them the same.
