On a Beretta, also made in the same area, xx indicates 1964. Interestingly enough Beretta also made a Model 409, as mentioned earlier. Beretta made many trade guns during that period without the trade style being shown on the gun. However PB would always appear on the barrels and the water table. Also, the proof mark of the in-circled star with PSF under it is the definitive proof for guns with smokeless powder and is used by Proof House in both Gardone and Brescia.
